What should come in place of the question mark (?) in the given series?
1514, 1513, 1517, 1508, 1524, ?

Given: 1514, 1513, 1517, 1508, 1524, ?

Logic: Difference is perfect squrae of natural number with alternating sign.

1513 − 1514 = −1

1517 − 1513 = +4

1508 − 1517 = −9

1524 − 1508 = +16

The next difference should be:

- 5²= - 25

Previous term = 1524

Next term = 1524 − 25 = 1499

So, the missing term is 1499.

Thus, correct option is (b).
