Question

an = 2n+1 then a5 = ?​

Answer 1

Answer:

a5 = 11

Step-by-step explanation:

an = 2n+ 1

Puting n=5

a5 = (2×5)+1

a5 = 10 + 1

a5 = 11

Answer 2

The value of a₅ will be 11.

Given:

the nth term of a series is given as: aₙ = 2n + 1

To Find:

we need to find the value of a₅

Solution:

we know the nth term of the series is given as aₙ = 2n + 1

to find the value of a₅, we substitute the value of n as 5 in the given equation to get-

a₅ = (2 × 5) + 1

a₅ = 10 + 1

a₅ = 11

Thus, the value of a₅ comes out to be 11.
