f(1) = 4 is given
f(n) = f(n-1)-4 is the recursive step or rule
f(2) = f(2-1)-4 ... replace n with 2
f(2) = f(1) - 4
f(2) = 4-4 ... replace f(1) with 4
f(2) = 0
----------
Repeat for n = 3
f(n) = f(n-1)-4
f(3) = f(3-1)-4
f(3) = f(2) - 4
f(3) = 0 - 4 .... replace f(2) with 0, which is from f(2) = 0 found earlier
f(3) = -4
---------
Repeat for n = 4
f(n) = f(n-1)-4
f(4) = f(4-1)-4
f(4) = f(3) - 4
f(4) = -4-4 ... plug in f(3) = -4
f(4) = -8
<h3>Answer is -8</h3>
Haddie wrote a check to the grocery store for $156.00. And turns out to only become 122.66 dollars the time she checked it later that night.Now, when she checked it in her banks, I believe there are fees charged to her written check. Now, let's find out how much will that be:=> 156 dollarss to 122.66 dollars=> 33.34 dollars=> 33.34 / 156 =0.21=> 0.21 * 100% = 21%<span>Thus, the bank opted 21% of her written check</span>
For the numbers in 
form, convert to polar form:
By DeMoivre's theorem,
For the numbers already in polar form, DeMoivre's theorem can be applied directly:
At second glance, I think the 2s in the last two numbers should also be getting raised to the 3rd and 4th powers:
