Question

the sum of three consecutive multiples of 7 is 63 find these multiples

Answer 1

let the 3 consecutive multiples be......x-7, x and x+ 7,
then according to the question
x-7+x+x+7 =63
=> 3x=63
=> x = 63/3 = 21
hence,these multipes are 14,21,28

Answer 2

Here is your solution

Let the three multiples be 7x, 7x+7and 7x+14

A/q

7x+7x+7+7x+14=63
21x+21= 63
21x=63-21
x=42/21
x=2

so.

7x = 14

7x+7 = 7×2+7 = 21

7x + 14 = 7×2 +14 = 28

The three consecutive multiples of 7 is 14, 21, 28
