Find two geometric means between 10 and 1250.

Finding two geometric means between 10 and 125:
a 1 = 10,  a 4 = 1250
a 4 = a 1 * q^3
1250 = 10 * q^3
q^3 = 1250 : 10
q^3 = 125
q = 5
a 2 = 10 * 5 = 50
a 3 = 10 * 5² = 10 * 25 = 250
The two geometric means are: 50 and 250, since 10, 50, 250 , 1250 forms a geometric sequence.
 

step-by-step explanation:

yes it is1. move over 2 points on the x-axis2. move over 2 points on the y-axis
