Find:

⇏ Find the number which is a multiple of 13 out of these numbers.

According to the question:

⇏ Let us assume x, x1, x2 as the consecutive numbers.

⇏ The sum of three consecutive numbers = 156.

Calculations:

⇏ $\sf x + x1 + x2 = 156$

⇏ $\sf 3x + 3 = 156$

⇏ $\sf 3x = 153$

⇏ $\sf x = 51$

The numbers are 51, 52 and 53. Therefore, 52 is the multiple of 13.
