Answer 1

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)

52 is  the multiple of 13.
So your answer will be 52.
