Suppose you have a sequence that begins {128, 64, 32, 16}. Give the next 3 numbers in your sequence. Use a recursive definition to define your sequence.

Question

I am having a hard time understanding how to solve these equations and writing them out in recursive.

Answer 1

Notice that each number is 1/2 of the previous.

What is 1/2 of 16?

Then continue for the next two.

 

a_n+1 = (0.5)a_n
