Answer:
$515.21
Step-by-step explanation:
Because you're compounding monthly, use the formula:

where A(t) is the amount after the compounding,
P = $500
r = .03 (always in decimal form!)
n = 12 (monthly is every month, and there are 12 months in a year) and
t = time in years
Filling in our given info:
which simplifies to
A(t) = 500(1 + .0025)¹² which simplifies to
A(t) = 500(1.0025)¹² which simplifies to
A(t) = 500(1.030415957) so
A(t) = $515.21
Answer:
$440
Step-by-step explanation:
Interest=Principal × Rate × Time/100(Formula)
We have to find the Interest.
Interest = $2000× 5.5 × 4/100
100 Interest = 44000
Interest = 44000/100
Interest = $440(Answer)
Let's analyze the increments for each step of the sequence:
Each step we add 3 to the previous number.
Since we need the 20th, from what we saw, in the 20th term we will have added three 20 times.
So the procedure is: calculate how much is 3 times 20 and then add that to the first term of the sequence.

So we add 60 to the first term to find the 20th term:
