So on my homework, there is a question that says:

Is it possible for the sequence t(n)=5*2^n to have a term with the value of 200? If so, which term is it? If not, justify your answer.

and another

Is it possible for the function f(x)=5*2^x to have an output of 200? if so, what input gives this output? If not, justify your answer.

If you do decide to help, show your work and explain why/why not please thanks.
