Part A: Write a function in for the geometric sequence where the first term is 11 and the common ratio is 4. Part B: Find the first five terms in the geometric function.

Part C: In one paragraph, explain your work from Step A and Step B.

Help please!!

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
