WebWe have confirmed that the sequence is arithmetic and d = 7, so we can use the formula for the sum of an arithmetic series by first finding the value of n. Using the explicit rule of an arithmetic sequence, we have the following: a n = a 1 … WebA recursive formula is a function that calls upon itself. For example: f (x) = f (x-1) + 3 In this function, you see that f (x) calls f (x-1) inside itself. This is recursive. An example of recursion in computer science is this: function test () { print ("Hello World"); test; } In this example, test calls upon itself just like in f (x).
