Question

find three consecutive multiples of 7 if their sum is -231​

Answer 1

Answer:

Step-by-step explanation:

Given,

Sum of multiples of 7 = 357

Let the numbers be x, x + 7 , x + 14

ATP,

x + x + 7 + x + 14 = 357

3x + 21 = 357

3x = 357 - 21

3x = 336

x = 336/3

x = 112

Therefore,

the numbers are 112, 119, 136
