Answer 2

Given,

625:169::729:?

To find,

Value in place of '?'

Solution,

Here, the given pattern is

625:169::729:?

Now if observed carefully, we can see that the 2nd number is the square of "the sum of digits of the first number". That is,

(6 + 2 + 5)² = (13)² = 169.

So, to find the number that replaces the '?', we need to add the digits of the previous number which is 729, and then square the number obtained. Thus,

7 + 2 + 9 = 18.

Now, since (18)² = 324, squaring the sum of digits of 729, that is,

(18)² will give us 324.

Therefore, the next number in the given sequence should be 324.
