Question

In the given series, how many times the two consecutive (one after another) number in the given sequence are square of the previous number?
$2,5,18,51,3,9,5,52,6,36,7,46,8,64,5,25,2,4,16,5,32,4,61,9,3,4,2$

• A. $4$
• B. $5$
• C. $6$
• D. $7$

Answer 1

The correct option is C $6$

In the given series, the pair of consecutive numbers in which one is square of previous number are $(3,9),(6,36),(8,64),(5,25),(2,4),(4,16)$

Thus, there are total $6$ times the two consecutive number in the given series are square of the previous number.

Hence, option C is correct.
