Arithmetic series

An arithmetic series has first term a and common difference d.
Enter a value for a and a common difference then enter positive number for n (greater than 2) for the number of terms you wish to create.
An arithmetic series is a linear pattern and when graphed forms a straight line.

  1. Create a arithmetic series that will generate the first 25 odd numbers.
  2. Create a series with the largest number is the first term and then 10th term is negative.
  3. Create a series that the common difference is a decimal value.

Enter a value for a :    Enter a value for d :    Enter a value for n :

To create another arithmetic series, enter new values for a, d, and n.

Summary

Any arithmetic sequence has this pattern a, a+d, a+2d, a+3d, a+4d... and so each term of the sequence can be expressed as: Termn = a+(n-1)d . This is a very useful formula.
