The question is an illustration of geometric progression.
- <em>The recursive function is: </em>
<em>.</em>
- <em>The explicit function is: </em>

From the question, we have:
<em /><em> ---- the first week</em>
<em /><em> ---- The rate at which the distance increases each week.</em>
When a sequence has a common ratio, the sequence is said to be a geometric sequence.
<u>The Recursive function.</u>
We have given that
---- the distance in the first week
The second week would be:
For the third week, the distance would be:
Express 2 as 3 - 1
Replace 3 with n, to get the distance for the nth week
Substitute 2 for r
Hence, the recursive function is:
<u>Explicit function</u>
The nth term of a geometric sequence is:
Substitute values for and r.
Hence, the explicit function is:
