To find:

The missing number

Solution:

The missing number is 18.

We can find the number by following the given steps-

We know that the numbers have a pattern that is to be followed throughout to find the missing term.

Let the missing number be X.

So, 64: 16::81: X.

On looking at the relation between 64 and 16, we see that

64=$8^{2}$, and

16=8×2

A similar relation will be followed between 81 and X.

We know that 81=$9^{2}$

So, X=9×2

X=18

The missing term, X=18.

So, 64:16::81:18

Therefore, the missing number is 18.
