Sal finds explicit formulas of arithmetic sequences given the first few terms of those sequences. He also explores equivalent forms of such formulas.
Solve problems such as: The first four terms in an arithmetic sequence are 12, 5, - 2, and -9. Find an explicit formula for the sequence.
In most arithmetic sequences, a recursive formula is easier to create than an explicit formula. The common difference is usually easily seen, which is then used ...
