This program allows you to solve problems dealing with number sequences.


* Information on the problems that can be solved by this program.

--------------------------------------------------

General

Find the desired value of a term in a sequence.

3,5,7,9.........

We want to find out the 34th term

First Term: 3 (a)
Common Diff: 2 (d)
Desired Term: 34 (n)

Result: 69

OR: 	a + (n-1) d
	3 + (34-1) 2
	3 + (33) 2
	33 * 2 + 3 = 69
--------------------------------------------------

Common Difference

Find the common difference between terms.

3_,_,9

First Term: 3 (a)
Last Term: 9 (l)
Number of Terms: 4 (n)

(l-a) / n
(9-3) / 4

9 - 3 = 6
6 / 4 = 1.5

--------------------------------------------------

Sum of series

Finds the sum of a series of numbers.

3,5,7,9

First Term: 3 (a)
Last Term: 9 (l)
Number of terms: 4 (n)


(a + l) 
 -----  * n
   2

3 + 9 = 12
12 / 2 = 6
6 * 4 = 24
