Question

which term of ap 3 8 13.....is 248 options are 50 25 28 49​

Answer 1

Answer:

Option A → 50 th term

Explanation:

Given,

AP → 3, 8, 13, ......

a n th term → 248

To Find → n

As,

a n th term → a + (n - 1)d

and

a = 3

d = +5

therfore,

3 + (n - 1)(5) = 248

3 + 5n - 5 = 248

-2 + 5n = 248

5n = 248 + 2

n = 250/5

→ n = 50
