Problem 2801. geometric progression

I've modified my previous program so that it now generates geometric progressions. For some reason, there's still always one wrong term. I'll blame it on my computer memory, it can't be my programming.

Once again, can you tell me the position of the wrong term, and return the correct sequence?

For example, given

errorsequence = [2 6 18 25 162]; %geometric sequence starting at 2 with ratio of 3

then

errorposition = 4;
truesequence = [2 6 18 54 162]; 

Note: The progression starts and ratio are integer only, so the sequence you return is expected to be made up of integers only.
