Use inductive reasoning to describe the pattern then find the next two numbers in the pattern 16,18,20,22

I see that 16 increases by 2 to get 18.

I see that 18 increases by 2 to get 20.

I see that 20 does the same to get 22.

SO - using inductive reasoning, I deduce that the number after 22 will be 24.

I deduce that the number after 24 will be 26.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
