The model n(t) = 2t represents the number of bacteria in a petri dish after t
hours, where t = 0 represents the time when the bacteria were first put into
the dish.
what is the correct value and interpretation of n(8)?

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
