I need help on a question its asking me for a pattern but it on exponents so the numbers are 1/125,?, 1/5, 1, 5,25,125,625,and what is the base riased by?

Well, It's increasing by a factor of 5, so your terms of the series are:

1/125 X 5=1/25 that's your 2nd. term, then multiply that by 5, you get 1/5, which is your 3rd.term, and multiply by 5 again and you get 1, which is your 4th.term.......on so on. Got it?.
