Correct Answer: 100


Solution : Given:
45, 46, 50, 59, 75,?

Add the square of the natural number in increasing order starting from 1 to get the required missing number –
45 + 1 2 = 46; 46 + 2 2 = 50; 50 + 3 2 = 59; 59 + 4 2 = 75; 75 + 5 2 = 100

So, the required missing number in the series is 100. Hence, the second option is correct.
