Question

if the nth term of AP is 5n+3 thn 3rd term of AP is??

​

Answer 1

Answer:

18

Step-by-step explanation:

There are two ways :

let n = 1

5(1)+3

8

let n = 2

5(2)+3

13

So, AP is 8, 13,....

So, a = 8, d = 5, n= 3

Now, an = a+(n-1)d

=8+(3-1)5

=18

-------------OR--------------

5(1)+3

8

let n = 2

5(2)+3

13

let n = 3

5(3)+3

18
