Question

The sum of three consecutive multiples of 7 is 147 find the multiples

Answer 1

Step-by-step explanation:

let the first number be x

They all are consecutive and multiple of 7

so , number are 7(x) + 7(x+1) + 7(x+2)

= 7(x) + 7(x+1) + 7(x+2)

= 21 x +21 = 147

= 21 x = 147 - 21

= 21 x = 126

= x = 126/21

= x = 6
