In the sequence:
64, 80, 100, 125,
the rate is:
80/64 = 1.25
100/80 = 1.25
125/100 = 1.25
So in the sequence, the rate of growth is 1.25
This in percent is 125%
Because 1.25 is te decimal form of a percent (which can be obtained by simply multiplying the growth decimal number by 100).
b.
112/64 = 1.75
196/112 = 1.75
343/196 = 1.75
So for this sequence, the rate of growth is 1.75 and it is common to all terms in the sequence. This in percent is 175%
Because 1.75 is te decimal form of a percent (which can be obtained by simply multiplying the growth decimal number by 100).
c.
128/64 = 2
256/128 = 2
512/256 = 2
The rate of growth is 2
This in percent is 200%
Because 2.0 is te decimal form of a percent (which can be obtained by simply multiplying the growth decimal number by 100).
d.
100/125 = 0.8
80/100 =0.8
64/80 = 0.8
The rate of growth is 0.8
This in percent is 80%
Because 0.8 is te decimal form of a percent (which can be obtained by simply multiplying the growth decimal number by 100).
