Question

The sum of three consecutive odd number is 165, what is the sum of the largest number and twice the smallest number ?

Answer 1

let 3 no be x, x+1, x+2
given that sum of three numbers=165
x, x+1, x+2=165
x, x, x=165-3
3x=162
x=162/3
x=54
x+1=54+1=55
x+2=54+2=56
verification
54+55+56=162
LHS=RHS
