Correct Answer: 78
Solution : Given: 63, 64, 60, 69, 53, ?
In the above-given series, add and subtract alternately the square of the consecutive natural numbers. 63 + 12 = 63 + 1 = 64 64 – 22 = 64 – 4 = 60 60 + 32 = 60 + 9 = 69 69 – 42 = 69 – 16 = 53 53 + 52 = 53 + 25 = 78
So, 78 is the missing number of the series. Hence, the fourth option is correct.
