Recursive Sequence
Arecursive sequenceis asequencein whichtermsare defined using one or more previous terms which are given.
If you know theterm of an arithmetic sequenceand you know thecommon difference,, you can find theterm using the recursive formula.
Example 1:
Find theterm of the arithmetic sequence if the common difference isand theterm is.
If you know theterm and thecommon ratio,, of ageometric sequence, you can find theterm using the recursive formula..
Example 2:
Write the first four terms of the geometric sequence whose first term isand whose common ratio is.
