This wizard is used to find the nth term of an arithmetic progression given the values of two terms of the sequence, ak and am.
It can be accessed by clicking on Wizard Button | Sequences | Find the nth term of an arithmetic progression using interpolation.
To determine the above:
- Fill the input boxes corresponding to k, ak, m, am and n. Note that "n" represents the position of the term you wish to find (for example, if you want to find the fifth term you will need to write n = 5).
- Click on the "Solve Step" button to see the next step or "Solve all" button to see all steps.
If you need an explanation for any particular step, click on the step and then click on the "Explain" button.
