What should come in place of the question mark (?) in the given series?

31, 32, 41, 66, 115, ?

Given: 31, 32, 41, 66, 115, ?​​

Logic: Difference of consecutive term is perfect square of odd number.

32 - 31 = 1 = 1^2​​

41 - 32 = 9 = 3²​

66 - 41 = 25 = 5²​

115 - 66 = 49 = 7²​

Next perfect square of odd number is: 81 = 9²​

? - 115 = 81​

115 + 81 = 196

So, the missing term is 196.

Thus, correct option is (c).
