Number Series Tips & Tricks
A question of number/wrong terms series
Direction: Find the wrong term in the given series: 800, 678, 579, 497, 434, 385, 349
- 494
- 385
- 800
- 579
- 349
Things to learn:
- Logics – Notice the pattern of the series. If it’s based on addition, subtraction, cubes, square, etc.
- Sequence to implement these logics – Follow a step-based protocol for recognizing the sequence.
Step-based protocol for sequences (Missing terms)
- Check if the sequence is based on square, cube, square +, sqaure -, cube +, cube –
- Check if the sequence is based on Multiplication +-, Division +-
- Look for double/triple series is being used
- Look for illogical series is given (rarely given)
Now look for logics as well during these steps. However, for wrong term series you can directly just follow the steps.
Percentage tips & tricks
- Learn about conversion of fraction into percentage
- Learn about conversion of percentage into fraction
- Focus on conceptual building as percentage can help you in solving a lot of quant questions apart from this very topic.
