Look at this series: 31, 29, 24, 22, 17, . . .

What number should come next?

What number should come next?

This is a simple alternating subtraction series, which subtracts 2, then 5.

Rule = (first number - 2), (second number - 5), (third number - 2), (fourth number - 5)...

Now The series is 31, 29, 24, 22, 17, . . .

(31 - 2 = 29), (29 - 5 = 24), (24 - 2 = 22), (22 - 5 = 17), (17 - 2 = 15)...

So the answer is 15..

In following questions, a sequence of groups of alphabets and numbers is provided with one term missing , Choose the missing term from options. DEF, HIJ, MNO, ?

The letters in each term are consecutive. There is a gap of one letter between the last letter of the first term and the first letter of the second term and a gap of two letters between the last letter of the second term and the first letter of third term. So, there would be a gap of three letters between the last letter of the third term and the first letter of the fourth term.
