<span>We are given f(1) = 0 and f(2) = 1.
Going forward, the term is the sum of the two previous terms.
f(3) = f(2) + f(1) = 0 + 1 = 1.
f(4) = f(3) + f(2) = 1 + 1 = 2
f(5) = f(4) + f(3) = 2 + 1 = 3
This matches answer B.</span>
The answer is 160 because as you stated in the question the number of bacteria doubles every five minutes, and after 10 minutes there are 40. Therefore, after 15 minutes there are 80 (40 doubled is 80), and after 20 (another 5 minutes), the number of bacteria is the double of 80, which is 160.

The answer is 80 because of 16 times 5 that's how you get your answer
hope this helps :)
Y=50+.05x
Just plug in the number of texts for x
y=50+.05(25)
y=51.25
^That was for 25 texts
Now just plug in all the other texts and replace that with x
Hope this helps!
