What is a possible value for the missing term of the geometric sequences?
2 answers:
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
The answer is:

C) 250</h2>

-0.91 is mostly likely the correlation coefficient for the set of data shown
The equation for this is y= -5/6 x +22/6
