Suppose you wanted to calculate the geometric mean of the numbers 2 and 32. This simple example can be done in your head. First, take the product; 2 times 32 is 64. Because there are only two numbers, the nth root is the square root, and the square root of 64 is 8.
12 1/2 (12x2+1)= 25/2
25/2 x 8/5 (we have to multiply8/5, not 5/8), so =200/10=20
answer is 20
Answer:
Step-by-step explanation:
x 
=
7 x 1 = 7
8 x 2 = 16
Let me know if this helps!
Answer:
The general form of geometric series is ⇒ 
Where a is the first term and r is the common ratio
The sum of n terms of the geometric series is ⇒ 
For the given geometric series 2, 8, 32, 128
The first term is a = 2
The common ratio r = 8/2 = 32/8 = 128/32 = 4
So, 
And the sum of the given terms:
n = 4
∴ 
Line<span> crosses the y-axis, b, called the y-intercept. when </span>graphing, put thisequation<span> into "y = " form to easily read </span>graphing<span> information. horizontal</span>lines<span> have a slope of zero - they have "run", but no "rise" -- all of the y values are 3.</span>
