Question

write the first four terms of ap if a=2and d=10
​

Answer 1

Answer:

Explanation:

Given: a = 2, d = 10

Let the series be a1, a2, a3, a4, a5 …

a1 = a = 2

a2 = a1 + d = 2 + 10 = 12

a3 = a2 + d = 4 + 10 = 14

a4 = a3 + d = 6 + 10 = 16

a5 = a4 + d = 8 + 10 = 18

the series will be 10,12,14,16,18 …

First four terms of this A.P. will be 12,14,16 and 18
