9-97.

A sequence starts $–3, 1, 5, 9, …$.

1. If you wanted to find the $50^{th}$ term of the sequence, would an explicit equation or a recursive equation be more useful?

Recall the definitions of explicit and recursive equations.

Explicit.

2. Write the equation in standard form as you did in problem 8-98.

Refer to problem 8-98 to recall what the standard form means.

$t(n) = −3 + 4(n − 1)$

3. What is the 50th term of the sequence?

Insert $50$ for $n$ in the equation you found in part (b).
