Question

Create an explicit equation for each recursively-defined sequence below.

Answer 1

Answer:

  t(n) = 3·5^(n-1)

Explanation:

The recursive formula describes a sequence in which each term is 5 times the one before it. This is a geometric sequence with common ratio 5 and a first term that is said to be 3.

As you know, the generic formula for a geometric sequence is ...

  an = a1·r^(n-1)

For a1 = 3, r = 5, and a sequence named "t", this is ...

  t(n) = 3·5^(n-1)

Answer 2

Answer:

t(n) = 3·5^(n-1)

Explanation:

im guessing this may not be right...
