Question

For an given A.P. a = 3.5, d = 0, n = 101, then tn = . . .
(A) 0
(B) 3.5
(C) 103.5
(D) 104.5

Answer 1

tn = a+(n-1)d
  
tn = 3.5+ (100)0
    = 3.5 + 0

Answer 2

Answer:

(B) 3.5

Step-by-step explanation:

As per the question,

Given data for A.P are as following:

First term = a = 3.5

Common difference = d = 0

Number of terms = 101

Formula used to find nth term is given as:

$T_{n}=a+(n-1)d$

Now put the given values, we get,

$T_{n}=a+(n-1)d$

$T_{101}=3.5+(101-1)(0)$

$T_{101}=3.5+0$

$T_{101}=3.5$

Hence, the required value if nth term is 3.5.

Therefore, option (B) is correct.
