Question

For An A.P. if a=3.5, d=0, then tn=?​

Answer 1

Step-by-step explanation:

tn=a+(n-1)d

tn= 3.5+(n-1)0

tn=3.5

Answer 2

For An A.P. if a = 3.5 , d = 0 , then tₙ = 3.5

Correct question : For An A.P. if a = 3.5 , d = 0 , then tₙ = ?

Given :

For An A.P. if a = 3.5 , d = 0

To find :

The value of tₙ

Formula Used :

The nth term of an AP is

tₙ = a + (n - 1 )d.

a = first term

tₙ = nth term

d = common difference.

Solution :

Step 1 of 2 :

Write down first term and common difference

For the given AP

First term = a = 3.5

Common Difference = d = 0

Step 2 of 2 :

Find the value of tₙ

tₙ

= nth term of the AP

= a + (n - 1)d

= 3.5 + (n - 1) × 0

= 3.5 + 0

= 3.5
