In an A.P., if $a = 3.5,\ d = 0,\ n = 101$, then find $a_n$.

Academic Mathematics NCERT Class 10

Given: In an AP, if $a = 3.5,\ d = 0,\ n = 101$.

To do: To find $a_n$.

Solution:

As given, $a = 3.5,\ d = 0,\ n = 101$

$\therefore a_n=a+( n-1)d$

$\Rightarrow a_n=3.5+( 101-1)0$

$\Rightarrow a_n=3.5+0$

$\Rightarrow a_n=3.5$

Thus, $a_n=3.5$.
