Find:11th term of the A.P. $10.0, 10.5, 11.0, 11.5, ……….$

Given:

Given A.P. is $10.0, 10.5, 11.0, 11.5, ……….$

To do:
We have to find the 11th term of the given A.P.

Solution:

Here,

$a_1=10.0, a_2=10.5, a_3=11.0, a_4=11.5$

Common difference $d=a_2-a_1=10.5-10.0=0.5$

We know that,

nth term $a_n=a+(n-1)d$

Therefore,

11th term $a_{11}=10.0+(11-1)(0.5)$

$=10.0+10\times0.5$

$=10.0+5.0$

$=15.0$

The 11th term of the given A.P. is $15.0$.
