Find the 7th term of A.P 2,5,8.................

Answer 1

Answer:

20 , I think

Step-by-step explanation:

given in question, a = 2 , d = 5-2 = 3 (=8-5, too)

let 7th term be n . then by

nth term formula

n = a + (n - 1)d

n = 2 + (7-1)3

n = 2+18

n = 20

here in formula,

a = first term of A.P.

n = 7 th term

d = common difference
