Find the next two terms of the sequence 37 29 21

By observing the current data in this sequence, we can create a function that represents this sequence.

f (x) = 45 - 8x

To find the 4th and 5th terms, we simply plug those values into the equation in place of x.

f (4) = 45 - 8 (4) = 13

f (5) = 45 - 8 (5) = 5
