Answer»

Hii
Here is Your answer
_______________________________________________________

Ist CONSECUTIVE multiple of 7 = x
IInd consecutive multiple of 7 = x + 7
IIIrd consecutive multiple of 7 = x + 14

A.T.Q

=> x + x + 7 + x + 14 = 777
=> 3x + 21 = 777
=> 3x = 777 - 21
=> 3x = 756
=> x = 756/3
=> x = 252

Hence, Ist consecutive multiples of 7 = x
= 252

IInd consecutive multiple of 7 = x + 7
= 252 + 7
= 259

IIIrd consecutive multiple of 7 = x + 14
= 252 + 14
= 266
