Question

if nth term of the ap is (3n+5)then common difference is​

Answer 1

Answer:

The common difference of the AP is 3

Step-by-step explanation:

given: nth term is 3n + 5

∴ a1 = 3(1) + 5 = 3 + 5 = 8

∴ a2 = 3(2) + 5 = 6 + 5 = 11

d = a2 - a1

=> d = 11 - 8 = 3

∴ d = 3

∴ The common difference of the AP is 3
