Answer 1

Answer:

1.5

Step-by-step explanation:

Average of 5 consecutive numbers is

x + x+1 + x+2 + x+3 + x +4

----------------------------------- = m

5

5x + 10 = 5m

x + 2 = m

x = m -2

Average of 8 consecutive numbers is

x + x+1 + x+2 + x+3 + x +4 + x+5 + x+6 + x+7

-----------------------------------------------------------------

8

= 8x + 28

---------

8

8(m-2) + 28 8m +12

= ------------------ = -------------- = m + 3/2
