1 Answer
Explanation:
Let,
The No. pf AMs inserted btwn.
this no. be
If we denote these AMs by
we conclude that,
Observe that the above AP has
To find its sum. we use the following Formula :
Sum=1/2(No. of Terms){First Term+Last Term}.
But, it is given that,
Using this, in
the desired No. of Ams. is
