Look at this carefully, it's the secret to solving arithmatic sequence equations. It simply states that the nth term is the first term plus n-1 times the difference between terms. Why n-1? Because for the first term, you don't add any difference. And for the second term you add just one, etc.
For your problem.



not time consuming.

This is an AP, and the formula for a term in an AP = , where:

 = A specific term, or term "n"

 = 1st term in the series 

n =   the sequence Number

d =   The common Difference, or the difference between terms



In this case,  becomes:  =======> 

nth term, or 

 ------ Substituting 10 for n

10th term, or
