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.
