Question

The nth term of the A.P.2,5,8...?​

Answer 1

ANSWER = 3n - 1

AP :- 2 , 5 , 8...

• first term , f = 2

• common

difference , d = 3

general formula for nth term = dn + f - d

applying here ,

nth term = 3n + 2 - 3

= 3n - 1

Answer 2

a = 2

d = a2 - a1

d = 5 - 2

d = 3

an = a + (n - 1)d

an = 2 + (n - 1)3

an = 2 + 3n - 3

an = 3n - 1

The n th term of an AP is 3n - 1
