Question

what are the three consecutive numbers of 7.if the sum of three consecutives is777​

Answer 1

Answer: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=  756/3

​  

=252

Multiples are 252,259,266.

Step-by-step explanation:

Answer 2

Answer:

Let the three consecutive multiples of 7 be 7x , 7(x+1) , 7(x+2)

7x + 7(x+1) + 7(x+2) = 777

7( x + x+1 + x+2)      = 777

7 (3x+ 3)                  = 777

3x + 3                      = 777/7

                               =111

3x + 3                      = 111

3x                            = 111 - 3

3x                           = 108

x                               = 108/3

                                = 36

Answer = Thus , 3 consecutive multiples of 8 are :

       1st multiple = 7*36

                           = 252

       2nd multiple=7*(36 + 1)

                            =7*37

                            =259

       3rd multiple=7*(36 + 2)

                           =7*38

                           = 266

Hope this helps you
