This is a pretty easy half life problaem.
There are formulas for calculating this using "e" but I have a simpler formula which you can find here:
http://www.1728.org/halflife.htm
Ending Amt = Beginning amount / 2^n
where n is the number of half-lives
n = 1
Ending Amt = Beginning amount / 2^1
Ending Amt = 1,000 / 2
Ending Amt = 500 grams

Answer:
Let a be the first term.
The sum is a1−r=33.25.
The second term is ar=7.98, so a=7.98/r.
Putting these together, 7.98/r(1−r)=33.25 or r(1−r)=0.24=0.6×0.4.
If the answer doesn't jump out at you from there, you could solve for r with the quadratic formula.

This product involves zero. So, you don't have to bother and compute all the factor, because if you multiply anything by zero you get zero.
