Question

If the sum of three consecutive integer is
30, then the middle number is :

Answer 1

Answer:

You can make an equation x + (x+2) +(x + 4) = 30. Then by combining like items, you get 3x + 6 = 30. Then solve, 3x = 30 - 6; then 3x = 24, and x = 8. So the 3 numbers are 8, 10 and 12

Answer 2

8

Step-by-step explanation:

let the first no.be x ,

second be ( x+2)

and,be ( x+4)

$x + (x+2) +(x + 4) = 30$

$3x + 6 = 30$

[we will get the step2 by solving the first equation].

$3x = 30 - 6 \\ 3x = 24 \\ x = 24 \3x = 8$
