Question

find the nth term 5,11,17,23​

Answer 1

Answer:

Given AP is 5,11,17,23,....

Here, first term =a=5

Common difference =d=11−5=6

Now,

n

th

term a

n

=a+(n−1)d

a

n

=5+(n−1)6

=5+6n−6

=(6n−1).

Answer 2

Answer :

a(n) = 6n - 1

To find : nth term of AP

Given :

a(1) = 5

d = 11 - 5 = 6

Formula used :

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

Solution :

=> a(n) = 5 + (n-1)6

=> a(n) = 5 + 6n - 6

=> a(n) = 6n - 1
