Because the number of frogs is increasing by the same ratio each year, this problem can be solved by the equation for a geometric progression. That equation is shown below:
xn = arn-1
where xn = the value of x after n terms
a = the initial value
r = the ratio of each term to the one before it (e.g. x2/x1)
For this case, we are starting with an initial value (a) of 100. After that there will be 5 more terms in the progression representing the value after each of the 5 years. So there are a total of 6 terms in the progression meaning that n= 6.
The ratio (r) which is the amount being multiplied each year is 1.22 because the rate is increasing by 22% each year.
Plugging these values for a, n, and r into the equation above gives:
xn = (100)(1.22)5
xn = (100)(2.7027)
xn = 270.3
Therefore, the value after 5 years is $270.27
The Emancipation Proclamation was a presidential proclamation and executive order issued by President Abraham Lincoln on January 1, 1863. In a single stroke, it changed the federal legal status of more than 3 million enslaved people in the designated areas of the South from "slave" to "free".
