Question 96045
1,2,4,8 is a geometric sequence. 
the commmon ratio (r) is the ratio of one term to the term in front of it.
{{{r=a[2]/a[1]=2/1=2}}} in this case.
To find the nth term: {{{a[n]=a[1]r^(n-1)}}}
{{{a[52]=1*2^(51)=2.2518*10^(15)}}}=$225,180,000,000. for the last weeks pay check.
For the total 52 wks pay is the sum of the geometric series which is:{{{a[1]((1-r^n)/(1-r))}}}
{{{(1-2^52)/(1-2)=4.5036*10^(15)}}}=$450,360,000,000.
