Answer 2

Hey,
Thanks for asking this question.

•Lets suppose first multiple number of 7 according to the question is P.

•So 2nd consecutive multiple of 7 = P+7

• 3rd consecutive multiple of 7 = P+14

But, according to the question,
P + (P+7) + (P+14) = 777
=> 3P + 21 = 777
=> 3P = 756

=> P = 252
&
=> P+7 = 259
&
P+14= 266

So three consecutive multiples of 7 are 252,259,266.

●Hope my answer helped.
