Answer 2

Step-by-step explanation:

an = 4n - 10

Thus, a1 = 4(1) - 10 = 4 - 10 = -6

a2 = 4(2) - 10 = 8 - 10 = -2

a3 = 4 (3) - 10 = 12 - 10 = 2

Now,

a2 - a1 = -2 - (-6) = -2 + 6 = 4

a3 - a2 = 2 - (-2) = 2 + 2 = 4

Therefore, a2 - a1 = a3 - a2.

Thus, it is an AP.

(i) a1 = - 6

(ii) d = 4

(iii) a16 = 4 (16) - 10 = 64 - 10 = 54

Hope it helps....
