Easy. This is where Mathematica's Functional programming is great.

factors = {1.10, 1.15, 1.20, 1.35}; 

FoldList[Times, 50, factors] 

{50, 55., 63.25, 75.9, 102.465}

I have a list of #s : 1.10, 1.15, 1.20, 1.35.

I start off with 50 and the first # is 50 * 1.10.
The second # is the first # * 1.15.
The third # is the second # * 1.20.
The fourth # is the third # * 1.35.

I want to maintain a list of these #s.
How can this be done efficiently in Mathematica without running for loops?
