Correct Answer: 196


Solution : Given:
25, 36, 49, 64, 81, 100, 121, 144, 169, ?

The numbers of the series are the squares of consecutive natural numbers starting from 5.
52 = 25; 6= 36; 72 = 49; 82 = 64; 92 = 81; 102 = 100; 112 = 121; 122 = 144; 132 = 169; 142 = 196

So, the missing number of the series is 196. Hence, the fourth option is correct.
