Question

the sum of three consecutive multiples of 7 is 777

Answer 1

Here is your answer

Let,
The three consecutive multiples of 7 be 7x, 7x + 7 and 7x + 14.

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

⇒21x + 21 = 777

⇒ 21x = 777 – 21

⇒ 21x = 756

⇒ x = 36


Number are:-

7x=7×36=252

7x + 7 = 252 + 7 = 259

7x + 14 = 252 + 14= 266


Hence,

The three consecutive multiples of 7 are 252, 259 and 266

here ur answer ⤵⤵⤵

⭐ let the three consecutive multiples of 7 is 7x, (7x +7) and (7x + 14 )

⭐7x + (7x +7 )+(7x +14) = 777

=> 7x + 7x +7 + 7x + 14 = 777

=> 21 x + 21 = 777

=> 21x = 777 - 21

=> 21 x = 756

=> x = 756/ 21

..° x =36

so, 7x = 252

(7x +7) = 7×36 +7 = 259

(7x + 14) 7 × 36 + 14 = 266

hence, three consecutive multiples of 7 is 252, 259 and 266..
