If you are preparing for the SSC MTS exam, you simply cannot ignore the Reasoning section. In Session 1 of the exam, Reasoning carries a massive weightage, and the “Series” topic guarantees at least 2 to 3 direct questions. Many students fear missing numbers and alphabet patterns, but the exam only asks basic 10th-level logic. These are easy, free marks! To make your preparation simple, we have provided exam-level Series questions with detailed solutions below. Practicing these, along with attempting our free topic tests, will definitely help you master this subject easily and quickly.
What to Study in Reasoning Series for SSC MTS?
A “Series” is simply a train of numbers or letters that follow a secret rule. You do not need to be a math genius to find this secret rule. You just need to look closely at the gap between the items. We can divide the whole Series syllabus into three simple parts:
- Number Series: You will see a line of numbers. You just have to find the gap (plus, minus, multiply) or check if they are simple squares (like 4, 9, 16).
- Alphabet Series: This is a game of A to Z. You just need to count how many steps the letters are jumping forward or backward.
- Continuous Pattern Series: You will see small letters with blanks like
a _ b c _ a b _. You just have to find the repeating rhythm or design.
If you just focus on these three simple patterns, Series will become your highest-scoring topic.
Important Series Questions for SSC MTS
Now you have understood what topics to study. But just reading theory is not enough. If you really want to score good marks, you should practice exam-level questions. Below, we have provided the top repeated questions divided by their types.
Q1. Find the next number in the series: 2, 4, 6, 8, ?
(A) 10
(B) 11
(C) 12
(D) 9
Answer: (A) 10
Explanation: This is a very simple series of even numbers. The rule is just adding 2. (8 + 2 = 10).
Q2. Find the missing number: 1, 4, 9, 16, ?
(A) 20
(B) 24
(C) 25
(D) 36
Answer: (C) 25
Explanation: These are squares of numbers in a line. 1² = 1, 2² = 4, 3² = 9, 4² = 16. So, the next will be 5² = 25.
Q3. Complete the series: 10, 15, 20, 25, ?
(A) 30
(B) 35
(C) 40
(D) 28
Answer: (A) 30
Explanation: Look at the gap. The numbers are jumping ahead by adding 5 each time. (25 + 5 = 30).
Q4. What comes next: 50, 45, 40, 35, ?
(A) 25
(B) 30
(C) 20
(D) 32
Answer: (B) 30
Explanation: The series is going backward. We are subtracting 5 from each number. (35 – 5 = 30).
Q5. Find the next number: 2, 6, 12, 20, ?
(A) 28
(B) 30
(C) 24
(D) 36
Answer: (B) 30
Explanation: Look at the gaps: +4, +6, +8. The gap is increasing by 2. The next gap will be +10. So, 20 + 10 = 30.
Q6. Complete the series: 3, 6, 12, 24, ?
(A) 36
(B) 40
(C) 48
(D) 30
Answer: (C) 48
Explanation: Every number is becoming double. 3×2=6, 6×2=12, 12×2=24. So, 24×2 = 48.
Q7. Find the missing number: 11, 13, 17, 19, ?
(A) 21
(B) 23
(C) 25
(D) 20
Answer: (B) 23
Explanation: These are continuous Prime Numbers (numbers that only divide by 1 and themselves). After 19, the next prime number is 23.
Q8. What comes next: 100, 90, 80, 70, ?
(A) 50
(B) 60
(C) 55
(D) 65
Answer: (B) 60
Explanation: The numbers are dropping by 10 each time. So, 70 – 10 = 60.
Q9. Find the missing number: 1, 8, 27, 64, ?
(A) 100
(B) 125
(C) 81
(D) 120
Answer: (B) 125
Explanation: These are cubes of numbers. 1³=1, 2³=8, 3³=27, 4³=64. The next will be 5³ = 125.
Q10. Complete the series: 5, 6, 8, 11, ?
(A) 15
(B) 14
(C) 16
(D) 13
Answer: (A) 15
Explanation: The gaps are +1, +2, +3. So, the next gap will be +4. (11 + 4 = 15).
5 Simple Tips to Prepare Series for SSC MTS
You do not need to be a topper to solve these questions. Just keep a cool head and follow these 5 easy tips:
- Learn A to Z Numbers: Memorize the position of English letters on your fingers. (A=1, B=2, Z=26). This will solve 90% of your alphabet series questions in seconds.
- Remember Squares up to 20: Learn the squares of numbers from 1 to 20 (like 2²=4, 5²=25, 10²=100). Railway and SSC exams love asking square number series.
- Always Find the Gap First: In a number series, do not panic. Just take a pencil and write the difference between the numbers. Most of the time, the gap itself holds the secret rule.
- Count the Blanks: In a continuous letter series, count total letters including the blanks. If there are 12 letters, break them into small groups of 3 or 4. You will see the pattern instantly!
- Practice Previous Year Papers: SSC MTS repeats the logic of Reasoning questions every single year. Solve the previous year’s series questions. You will see that they are very easy.

FAQs: Reasoning Series Questions for SSC MTS Exam
No, not at all! The reasoning section in the SSC MTS exam is exactly of the 10th-pass level. The series questions are very basic and check your normal logic, not high-level mathematics.
You can comfortably expect 2 to 3 direct questions from Number, Alphabet, and Pattern series combined.
Here is a big relief for you! In the SSC MTS exam, Session 1 (which includes Math and Reasoning) has NO negative marking. You must attempt all questions without any fear.
You do not need to memorize huge numbers. Just remembering the cubes from 1 to 10 (like 2³=8, 3³=27) is more than enough for this exam.
Write down the A to Z alphabets with their numbers (1 to 26) on your rough sheet as soon as the exam starts. You can look at it and find the gaps instantly without counting on your fingers.
If you cannot find the gap or rule within 30 to 40 seconds, leave it and move to the next question. Do not waste time. You can always come back to it at the end of the paper.
