Question

The sum of three consecutive 0dd numbers is 51. Find the number.

Answer 1

Let the three consecutive odd numbers be x-1,x and x+1.

According to the question,

»x-1+x+x+1=51
»3x=51
»x=51/3
»x=17

Therefore, x-1=17-1=16
x=17
x+1=17+1=18

Therefore the sum of the numbers 16,17 and 18 is 51.
