# How to Solve Problems Based on Nth term /General Term of Arithmetic Progression

**In previous video we learnt the derivation of general term or nth term of an Arithmetic progression. **

**Now in this lesson we will use the application of the nth term formula of arithmetic progression .**

In this video you will see the letter so small so I suggest you to watch this video with full zoom . Can’t you find its and the bottom of the right corner, click on that it will be full screen.

Well, in this video we solve some problems related to nth term of Arithmetic Progression.

Hope, you have a pen and paper. So let’s begin our lesson.

**Hmmm … Now I think you got a little idea.
WE LEARNT
1. In the nth term formula of arithmetic progression there are four (4) variables, you will get any three variables you have to find the fourth one which is missing.
2. To find the 4th variable it may be first term (a), last term (l), term number (n), nth term, or may be common difference so just put all the given value in the formula of nth term of arithmetic progression you will get the required thing easily.**

Friend you will be perfect if you solve these problems:

Q1. Find the 12th, 24th, and nth term of an A. P. given by , 9, 13, 17, 21, 25, …

Q2. Show that the sequence 9, 12, 15, 18, ……… is an arithmetic progression. Find its 16th term and the general term.

Q3. The first term of an Arithmetic progression is -7 and the common difference 5. Find its 18th term and the general term.

Q4.Determine the 10th term from the end of the Arithmetic progression 4, 9, 14, ……………….., 254.

Q5. Whci term of the arithmetic progression 4, 9, 14, 19, ……………is 124 ?
