You use the arithmetic sequence formula and input the information given to you.
tn = a + (n-1)d
t(56) is what your looking for so don't worry about the tn.
a is your first term,
a = 15.
n is the position of the term you are looking for, n = 56.
And d is the common difference, you find this by taking t2 and subtracting t1. t2=18 and t1=15.
d = 18 - 15 = 3
Inputting it all into the formula you get,
t(56) = 15 + (56-1)(3)
term 56 = 180.
You use this formula to find any term in a sequence provided you are given enough info. You can also manipulate it if you are asked to find something else like the first term(a), common difference(d) or term position(n). It just depends on what the question is asking and what information you are given. :)
Hope this helps!

The formula for circumference is 
or 
. We have a diameter for the semicircle, so let's use the diameter formula. 
which is either 
or C = 5.338 if we multiply pi in as 3.14. BUT this is only half a circle, so we only have half that distance around the outside. Therefore, the circumference of half this circle is 2.669 cm. But we need to add the 24 mm in. 24 mm in centimeters is 2.4 cm. So 2.669 + 2.4 = 5.069
Answer:
First bank = $6792
City bank = $6803
Star bank = $6817
Step-by-step explanation:
The lists of banks and their annual interests rates are attached.
For first bank, since the interest is 7.5%, The total interest = 7.5% of $20000 = 0.075 × $20000 = $1500
For city bank, since the interest is 8.2%, The total interest = 8.2% of $20000 = 0.082 × $20000 = $1640
For Star bank, since the interest is 9%, The total interest = 9% of $20000 = 0.09 × $20000 = $1800
The loan plus interest for the banks annually are:
First bank = $20000 + $1500 = $21500
City bank = $20000 + $1640 = $21640
Star bank = $20000 + $1900 = $21900
The monthly payments for the banks are:
First bank = $21500 / 12 months = $1792
City bank = $21640 / 12 months = $1803
Star bank = $21800 / 12 months = $1817
Since The cost to run the gym each month is $5,000. Ed's total monthly expenses for each loan option = monthly payments + cost for each month. It is calculated as:
First bank = $5000 + $1792 = $6792
City bank = $5000 + $1803 = $6803
Star bank = $5000 + $1817 = $6817
