Question

b. The sum of three consecutive multiples of 7is 126​

Answer 1

Hey mate !!

The sum of three consecutive number be X = 7 .

so, the number = X,X+1,And X+2

According to the problem,

(X+X+1+X+2)7 = 126

=>(3X+3)7= 126

=> 7×3(X+1) = 126

=> 21(X+1) = 126

=> X+1 = 126 /21

=> X = 6-1

=> X = 5

:• The Sum of the three consecutive multiple of 7 are

7x = 7×5 = 35

7(X+1) = 7( 5+1) = 42

7(X+2) = 7(5+2) = 49
