Question
In an AP, if a = 3.5, d = 0, n = 101, then an will be ______.
Options
0
3.5
103.5
104.5
Solution
In an AP, if a = 3.5, d = 0, n = 101, then an will be 3.5.
Explanation:
We know that nth term of an AP is
an = a + (n – 1)d
Where,
a = first term
an is nth term
d is the common difference
an = 3.5 + (101 – 1)0
= 3.5 ...(Since, d = 0, it’s a constant A.P)
