5-121.

Think about the difference between a function and a sequence as you answer the questions below. Homework Help ✎

A certain sequence has an explicit equation of

*t*(*n*) = 5 · 2. Is it possible for this sequence to have a term with the value of 200? If so, which term is it? If not, justify why not.^{n}Now think about a function with the equation of

*f*(*x*) = 5 · 2. Is it possible for this function to have an output of 200? If so, what input gives this output? If not, justify why not.^{x}

(200) = 5·2^{n}

Solve the same equation as shown in part (a);

Can *x *≈ 1.4427 be a possible input for a function?
