The sum of three consecutive multiples of 7 is 777. Find the multiples.

Answer»

Step-by-step explanation:

let the THREE consecutive MULTIPLES be 7x, 7x+7, 7x+14

the SUM of three consecutive multiple is 777

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

21x + 21 =777

21x = 777 -21

21x = 756

x = 756/21

x= 36

substitute x

7x= 7 (36)= 252

(7x + 7) = 7(36) + 7 = 259

(7x +14 ) = 7 (36) + 14 = 262

therefore the three multiples are 252, 259, 262
