Question of The Day18-03-2021

Find the missing term (?) in the series.
12, 5, 25, 29, 85, ?
 

Answer

Correct Answer : a ) 89

Explanation :

Consider the given series:

12, 5, 25, 29, 85, ?

In the above series, the next term is the sum of the squares of the digits of the previous term.

Thus,

5 = 12 + 22

25 = 52

29 = 22 + 52

85 = 22 + 92

Missing term (?) = 82 + 52 = 64 + 25 = 89

Thus, missing term = 89

Hence, (a) is the correct answer.
