Question

find three consecutive odd number whose sum is 45

Answer 1

let the three consecutive odd number be x, x+2, x+4.
ATQ, x + x + 2 + x + 4 = 45
3x + 6 = 45
3x = 45 - 6
3x = 39
x = 13
now the numbers are :-
1. x = 13
2. x + 2 = 13 + 2 = 15
3. x + 4 = 13 + 4 = 17

Answer 2

Let the no.s be x,x+2,x+4
.•. x+x+2+x+4 = 45
3x+6 = 45
3x = 45-6
x = 39/3
.•. x = 13
x+2 = 13+2 = 15
x+4 = 13+4 = 17
