the 2nd term in a geometric sequence is 20 the 4th term in the same sequence is 45/4 or 11.25 what is the common ratio?
lbvjy [14]
Let x be the common ratio and y be the 3rd term

11.25/x=y     This means the fourth term divided by the common ratio will get the third term
20x=y           This means the second term multiplied by the common ratio will get the third term

11.25/x=20x        Set the two y's equal to each other, and solve for x!
20x^2=11.25
x^2=.5625
x=+-√.5625
x=.75 or -.75
