let the multiples be x,x+7,x+14
according to the problem,
x+(x+7)+(x+14)=777
3x + 21 = 777
3x=756
x=252
therefor the multiples are 252,259,266

Numbers are 252, 259, 266

Given : Sum of Three Consecutive Multiples of 7 is 777

To Find : Three Numbers

Step By Step Explanation :

The Three consecutive multiples of 7 will be \textsf{x, x + 7} and \textsf{x + 14}. As their Sum is 777, We can write it as follows :

\longrightarrow\textsf{x + (x + 7) + (x + 14) = 777}

\longrightarrow\textsf{x + x + 7 + x + 14 = 777}

\longrightarrow\textsf{3x + 7 + 14 = 777}

\longrightarrow\textsf{3x + 21 = 777}

\longrightarrow\textsf{3x + 21 - 21 = 777 - 21}

\longrightarrow\textsf{3x = 756}

\longrightarrow\textsf{x = 756/3}

\longrightarrow\textbf{x = 252}

  • Now Three Numbers are \textsf{x, x + 7} and \textsf{x + 14}. Substitute the value of x in each and we get 252, 259, 266.

Therefore, Numbers are 252, 259, 266
