This is a geometric sequence because each term is twice the value of the previous term. So this is what would be called the common ratio, which in this case is 2. Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a(n)=nth value, a=initial value, r=common ratio, n=term number
In this case we have r=2 and a=1 so
a(n)=2^(n-1) so on the sixth week he will run:
a(6)=2^5=32
He will run 32 blocks by the end of the sixth week.
Now if you wanted to know the total amount he runs in the six weeks, you need the sum of the terms and the sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r) where the variables have the same values so
s(n)=(1-2^n)/(1-2)
s(n)=2^n-1 so
s(6)=2^6-1
s(6)=64-1
s(6)=63 blocks
So he would run a total of 63 blocks in the six weeks.

Answer:
it's either a or b, but I would go with A
Answer:
A≈18.38
Step-by-step explanation:
Solve for area

Round answer
Hope this helps.
To find the answer we need multiply the number of containers by number tons of sugar each container has.
(4 1/3 )*(2 1/7).
To calculate , we need to convert mixed numbers into improper fractions.
4 1/3 = (4*3 +1)/3 = 13/3
2 1/7 = (2*7+1)/7 =15/7
(4 1/3 )*(2 1/7) = (13/3) * (15/7) = (13*5)/7 = 65/7 = 9 2/7 (tons)
Answer: 9 2/7 tons.
