Question

the sum of the three consecutive multiple of 7 is 777.find these number

Answer 1

The given number is 777=7(111)=7(36+37+38).
Therefore the numbers are
36*7,37*7,38*7

=252,259,266

Answer 2

Answer:

252,259 and 266

Step-by-step explanation:

Let the first multiple be 7 x.

So, the next consecutive multiple will be 7 x + 7 and the next consecutive multiple thus will be 7 x + 14.

Now , given sum is 777.

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

=>21 x = 777-21=756

=>x=756/21=108/3=36

Thus, the required numbers are (36*7=)252, 259 and 266
