Answer 1

Answer:

Step-by-step explanation:

let x be the first multiple of 7g

Answer 2

Step-by-step explanation:

consider first number x

second consecutive multiple of 7=x + 7

third consecutive multiple of 7 = x + 14

according according to the question,

x+(x+7)+(x+14)=777

x + x + 7+ x + 14 =777

3x+21=777

3 x = 777 - 21

3x =756

dividing both sides by 3

3x/3 = 756/3

x= 252

first number x=252

second number x + 8 = 252+8=260

third number x + 16 = 252+16=268
