4. GENERAL OR NTH TERM IN AN ARITHMETIC PROGRESSION  
We can always find a formula which allows us to find any term in any arithmetic progression, as long as we know its position in the sequence. This formula is denoted as the general or nth term of the arithmetic progression. 

9. Examine the sequence in the window by going through the following steps:


5. DETERMINING THE GENERAL TERM OF AN ARITHMETIC PROGRESSION  
We are going to find the general or nth term of the following arithmetic progressions. 

10. Copy the following arithmetic progressions into your exercise book and work out the general term:
Write down the first term a_{1}_{ }and the common difference d in each case, apply the general formula and carry out the operations indicated. The results can be checked in the window.
