Answer 1

Answer:

252,259 and 266

Step-by-step explanation:

let the smallest of those three numbers be x

the 2nd number will be x + 7

and the third will be x + 7 + 7  =  x + 14

The equation can be formed as:

x + x + 7 + x + 14 = 777

3x + 21 = 777

3x = 756

x = 252

x + 7 = 259

x + 14 = 266

Answer 2

$\huge\red{\underline{\overline{\mathbb{√\ηsωεя:-}}}}$

As given,the three consecutive multiples of 7 will be of the form: $x,x+7 and x+14$

Then according to the question,

$x+x+7+x+14=777$

$3x+21=777$

3x=756

x = 252

Multiples are 252,259,266.
