what is a recursive formula for this sequence. Warmup 1 Find f5 if fn n and f1 -2 n f 1 2 Write a recursive formula for. Recursive sequences are sometimes called a difference equations.
In order to efficiently talk about a sequence we use a formula that builds the sequence when a list. As with any recursive formula the first term must be given. Y -3 B.
A 1 5.
15 25 125 625. Instead it helps to be observant of the patterns exhibited by a given sequence and use the initial values to create a rule that may apply to the sequence. Each term is found by doing something to the terms immediately in front of that term. Then a recursive formula for this sequence will be needed to compute all the previous terms and find the value of t n.
