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.
