Answer 2

Answer:

Observations= X,X+2,X+4,X+6,X+8

No of observations=5

Mean of observations= 13

Sum of observations= Mean of observations × No of observations

= 13 × 5 = 65.

Sum of observations in terms of X = X+2+X+4+X+6+X+8 = 5X+20

According to the problem

5X + 20 = 65

5X = 65 — 20

5X = 45

X = 9

The value of X is 9.
