Evaluating the given sequence, it is evident that the next number is twice the number prior to it. Thus, the given is a geometric sequence with first term (a1) equal to 1 and common ratio of 2. The geometric series may be calculated by the equation,
Sn = a1 x (1 - r^n) / (1 - r)
where Sn is the sum of n terms in this case, n = 11.
Substituting the known values,
<span> Sn = 1 x (1 - 2^11) / (1 - 2) = 2047
</span>
Thus, S11 is 2047.

The person that saves the most money every month is given as Jerry
<h3>How to solve for the savings</h3>
We have to solve for 35 percent of 5 dollars
= 0.35 * 45
= 1.75
This is the amount that Tom saves
The question tells us that Jerry spends 2/5 of his, hence he would save 2/5
then we have 2/5 * 5
= 2
Therefore we have that Jerry is the one that saves the most money because he saves 2 dollars.
Complete question
Tom and Jerry both earn the same monthly salary.
Each month
Tom saves 35% of his salary.
Jerry spends 3/5
of his salary and saves the rest of his salary.
Work out who saves the most money each month.
You must show your working.
