Answer 4

hmm.

year 1 there are 5*4^(1-1) = 5 frogs
2 5*4^(2-1) = 20 frogs
3 5*4^(3-1) = 80 frogs

Answer 5

So which one do you think ?

Answer 6

5 , 20 , 80

Answer 7

you get the nest value by multiplying by 4, right?

Answer 8

Okay...I think that it is D

Answer 9

Sorry about it taking so long...my internet is slow

Answer 10

no
increasing by 4 means you ADD 4 each year

Answer 11

- we are MULTIPLYING by 4

Answer 12

Oh wait...it is B

Answer 13

Because you are adding 4 time the amount of frogs each year
