This video provides two examples of how to find the terms in a sequence given an which is a recursive sequence formula. For instance f x f x 1 2 is an example of a recursive sequence because f x defines itself using f. Along with the interpretation for each part.
A 2 50.
F 1 5. Figure out the common difference Pick a term in the sequence and subtract the term that comes before it. There exist two distinct ways in which you can mathematically represent a geometric sequence with just one formula. There isnt a formula into which you could plug n 39 and get the answer.
