18. 12/4 =3, 36/12 =3 the ratio is 3
19. 108/162 =0.667, 72/108= 0.667 the ratio is 0.667 or 2/3
20. 2/3 / 4/3 = 1/2, 1/3 /2/3 = 1/2, the ratio is 1/2
5m-8=3m+8
(Plus the '8' to both sides)
5m=3m+16
(Subtract '3m' from both sides)
2m=16
(Divide by 2)
m=8

Why? Bc it is the closest 4,751
A geometric sequence is a sequence with a common ratio multiplied by previous term to give the next. Lets call x the common ratio, so we know that 4 was multiplied by x to give the second term, and so forth until it was multiplied again and again by x until the 16384 was reached which happens to be the 13th term, that means that 4x was multiplied by x 12 more times to give 16384, that is:
4x^12 = 16384
x^12 = 4096
x = 4096^-12
x = 4.48 x 10^-44
that is the common ratio
