Answer 2

Given:

Seven consecutive integers are given,

average of first five integers $=25$

To Find:

Average of all the seven integers.

Solution:

let the consecutive integers be

$x,x+1,x+2,x+3,x+4.x+5,x+6$

$x+2$ is the average of first five consecutive integers,

∴$x+2=25$

∴$x=23$

$x+3$ is the average of all the seven numbers.

∴ $x+3=23+3$

            =$26$

Hence the average of all the seven numbers is 26.
