Answer 1

heya friend here's ur answer :-)

Let the first number be X ,
then the second and third number are-X+1,X+2
Given,
X+(X+1)+(X+2)=156
3X+3=156
3(X+1)=156
X+1=156/3=52
X=52-1=51. (that is the first number)
X+1=52. (that is the second  number)
X+2=53. (that is the  third number)

A/Q,

51 is the multiple of 3 out if these numbers.

hope it helps

Answer 2

Here is your solution

Given :-

The sum of three consecutive numbers is 156

Let consecutive number be x ,x+1,x+2

A/q

=>x+(x+1)+(x+2)= 156
=>3x+3=156
=>3x=156-3
=>3x = 153
=>x=51

The three consecutive numbers is

x = 51

x +1 = 51+1 = 52

x+2 = 51+2 = 53

The three consecutive numbers is 51,52,53

Hence

52 is multiple of 13✔

Hope it helps you
