Answer 2

would this be 10

Answer 3

i mean d

Answer 4

ratio = 2nd term / 1st term

So the 2nd term = 10^-2 which is the same as 0.01
1st term = 1
So ratio = 0.01/1 = ?

Answer 5

0.01 right

Answer 6

yeep

Answer 7

wait how tho

Answer 8

look at your picture...
what is the first term in your sequence?
What is the second term in your sequence?

Answer 9

1meter and 10^-2m

Answer 10

yeppp.
To find the ratio you do 2nd term divided by 1st term...
So 10^-2 / 1 = ?

Answer 11

0.01

Answer 12

yep :) that's why we got 0.01

Answer 13
