<u>Arithmetic Sequences </u>
The arithmetic sequences are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
The sum of the n terms of an arithmetic sequence is given by:
We are given the first two terms of the sequence:
a1=5, a2=8. The common difference is:
r = 8 - 5 = 3
Thus the general term of the sequence is:
The formula for the sum is:
Operating:
Since there are 60 seconds in one minute, we can form the equation:
From here, we can cross multiply.
The train would travel 10,800 feet in one minute.
From here, we can cross multiply.
The train would travel 10,800 feet in one minute.
The amount to be paid after 3 years is $23,329.97.
<h3>What is Compound Interest?</h3>In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest.
Given:
P= 20,000
r= 5.2%
t= 3 years
r = R/100
r = 5.2/100
r = 0.052 rate per year,
Now, solve for A
A = P
A = 20,000.00
A = 20,000.00
A = $23,329.97
