Each of these terms is a logarithm of 125 to bases of 1/5, , and . Frankly, I don't see a patternunlessthere is a missing in there. If that were the case, then the nth term would be .

The whole point of a logarithm is that . If the nth term is indeed , then . The nth term would be .

?? Surely, that is wrong. It must be like the others. In that case, each is the logarithm of 64 to bases , , and . The nth term would be . . .log_{4}(64) , log_{8}(x) , log_{32}(64)

Also describe how to obtain the third answer in each row from the first two answers.
