Question

The sequence -3,1,5,9 will be an AP, if the 5th term is........

Answer 1

Answer:

5th term is 13.

Step-by-step explanation:

Given AP series,

-3, 1, 5, 9,..

first term, a = -3

common difference, d = (1-(-3)) = (5-1) = (9-5) = 4

we have to find 5th term, n = 5

In an AP,nth term is given by,

=> a(n) = a + (n - 1)d

    a₅ = (-3) + (5 - 1)(4)

    a₅ = -3 + 4(4)

    a₅ = -3 + 16

    a₅ = 13

=> 5th term is 13
