A(n)=ar^(n-1) and we can find the rate upon using the ratio of two points...
50/1250=1250r^2/1250r^0
1/25=r^2
r=1/5 so
a(n)=1250(1/5)^1=250
...
You could have also found the geometric mean which is actually quite efficient too...
The geometric mean is equal to the product of a set of elements raised to the 1/n the power where n is the number of multiplicands...in this case:
gm=(1250*50)^(1/2)=250
Answer:
Step-by-step explanation: 6a squared
A) I=PRT
I=3000(.12)(2)
I=$720
"More than" is codeword for addition. In this case, since this is "x more than 5", <u>our expression is 5 + x, or C.</u>
