Question

The sum of three consecutive odd numbers is 57 .find the number

Answer 1

Let three consecutive no. Be x, x+1 & x+2
Acc. To the question

x + (x+1) +(x+2)= 57
x+ x+1+ x+2 = 57
3x + 3 = 57
3x = 57-3
3x = 54
x = 54/3
x = 18

So the three no. Are,
x = 18
x+1 =18+1 =19
x+2 = 18+2 =20

Answer 2

Let three consecutive no. Be x, x+1 & x+2
Acc. To the question

x + (x+1) +(x+2)= 57
x+ x+1+ x+2 = 57
3x + 3 = 57
3x = 57-3
3x = 54
x = 54/3
x = 18

So the three no. Are,
x = 18
x+1 =18+1 =19
x+2 = 18+2 =20
