Question

The sum of 6 consecutive intergers is 519 what is the third number in this sequence

Answer 1

let x be the first integer, then

:

x + (x+1) + (x+2) + (x+3) + (x+4) + (x+5) = 519

:

6x + 15 = 519

:

6x = 504

:

x = 84

Our sequence is

:

84, 85, 86, 87, 88, 89

Answer 2

Six consecutive integers are as

x+x+1+x+2+x+3+x+4+x+5=519

6x+15=519

6x=504

x=84

So third no. Will be x+2=84+2=86
