Excel中的公式以百分比X的倍数递增

Question

I have a pretty simple problem I am trying to solve, but can't figure it out and can't even think of what to put in google.

I have two cells in excel. One (A1) will have a number, say from 0-100. In the other (A2) I want to start with 15 when A1 is 0, and increment by 15% for each increase in A1. Here is what should show at various points:

A1 - A2
0 - 15
1 - 17.25
2 - 19.8375
3 - 22.81313
...
10 - 60.68337
...
20 - 245.4981

and so on... Basically in this form it is just the cell above * 1.15. But I can't figure out how to condense that into a single formula.

Answer 1

Using a more "standard" spreadsheet nomenclature:

   |     A           B
---+-----------+-----------
 1 |         0          15
 2 |         1       17.25
 3 |         2     19.8375

If you just want the cell to be 15% more than the cell above it, put in (for example) B2 :

= B1 * 1.15

and copy that to all other B cells below B2 .

If you want it based on An (if, for example, the A cells may not be consecutive), you can use powers (again in B2 ):

= B$1 * (1.15 ^ A2)

though I'm wasn't entirely sure if ^ is the exponentiation operator in Excel, I've long since switched to Gnumeric. A quick web search seems to indicate that it is the correct operator.
