Find the common ratio for the series 64, 48, 36, 27, …
A. 2/3
B. 3/4
C. 2/5
D. 1/4

B. 3/4

Step-by-step explanation:

64 x 3/4=48

48 x 3/4=36

and so on...

B 3/4

Step-by-step explanation:

The nth term of a geometric progression is given by

an = a1 . rn - 1

Where;

an = the nth term

a1 = the first term

r = common ratio

n = the number of terms in the series

Common ratio, r = the ratio of the second term to the first term

= a2 : a1

Given from the series,

a2 = 48

a1 = 64

Common ratio, r = 48 : 64

= 48/64 = 3/4

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
