Question

Sum of Three consecutive odd numbers is 63 .find the number

Answer 1

Let the three consecutive odd Numbers be x, x+1,x+2
X+x+1+x+2 = 63
3x + 3 = 63
3x= 60
X= 20

The numbers are = 20,21,22

Answer 2

We know that consecutive odd number differ by 2 so,

Let the three consecutive odd numbers be x, ( x + 2 ) and ( x + 4 ) respectively.

We can derive the following equation by reading the question carefully,

x + ( x + 2 ) + ( x + 4 ) = 63
x + x + 2 + x + 4 = 63
3x + 6 = 63
3x = 63 - 6
3x = 57
x = 57 / 3
x = 19

Therefore we can calculate the consecutive odd numbers now:

First Consecutive Odd Number = 19
Second Consecutive Odd Number = 19 + 2 = 21
Third Consecutive Odd Number = 19 + 4 = 23
