1.	Find the mean of x, x+2, x+4, x+6 and x+8. If the mean of first two terms is 10
Answer» Answer: BY FORMULA, MEAN OF TERMS = SUM OF TERMS / NUMBER OF TERMS Mean of first TWO terms = 10 (x+x+2)/2 = 10 2x+2 = 20 2x = 18 x = 9 Mean of all terms = (x+x+2+x+4+x+6+x+8) / 5 = (5x + 20)/5 = x+4 = 9 + 4 = 13

Find the mean of x, x+2, x+4, x+6 and x+8. If the mean of first two terms is 10

Answer»

Answer:

BY FORMULA,

MEAN OF TERMS = SUM OF TERMS / NUMBER OF TERMS

Mean of first TWO terms = 10

(x+x+2)/2 = 10

2x+2 = 20

2x = 18

x = 9

Mean of all terms = (x+x+2+x+4+x+6+x+8) / 5

= (5x + 20)/5

= x+4

= 9 + 4 = 13
