Question

The sum of three consecutive integers add up to 51 find these multiples

Answer 1

Let three consecutive integers be x,x+1 and x+2

Three consecutive integers add up to 51.

x+x+1+x+2 = 51

3x+3 = 51

3(x+1) = 51

x+1 = 51/3

x+1 = 17

x = 17-1

x = 16

x = 16
x+1 = 16+1 = 17
x+2 = 16+2 = 18

The three consecutive integers are 16,17 and 18.

Hope it helps

Answer 2

Let the number be = x
Then, 3 consecutive integers are = x, x+1, x+2
Their sum = 51
So, (x) + (x+1) + (x+2) = 51
3x + 3 = 51
3x = 51 - 3
3x = 48
x = 48÷3
x = 16
So, 16 , 16+1 , 16+2
Therefore, 16, 17, 18
