Answer:

Step-by-step explanation:

Given,

a+2d = 4.   --eq. 1

a + 8d = 8.

By Using Eliminating Method Of Simultaneous Equations,

-6d = -4.

d =4/6.

d = 2/3.

d = 0.6

From eq. 1,

a + 2(0.6) = 4

a + 1.2 = 4

a = 4 - 1.2

a = 2.8

l = a + (n-1)d

0 = 2.8 + (n-1)0.6

0 = 2.8 + 0.6n - 0.6

0 = 2.2 + 0.6n

0.6n = -2.2

n = -2.2 / 0.6

n = 3.6

As The Term No. Is In Whole Number.

Therefore, 0 is Not in The Given A.P.

10. (a+16d) - (a+9d) = 7.

a+16d - a -9d = 7.

16d - 9d = 7.

7d = 7.

d = 7/7.

d = 1.
