One approach is to use FoldList: In[1]:= FoldList[Times, 50, {1.10, 1.15, 1.20, 1.35}] Out[1]= {50, 55., 63.25, 75.9, 102.465} In[2]:= FoldList[Times, 50, {a, b, c, d}] Out[2]= {50, 50 a, 50 a b, 50 a b c, 50 a b c d} --David On Feb 20, 2:47 am, Clutch <clutchderivat... at gmail.com> wrote: > 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?
