Question

oleg3321 · Answer

Bill is able to save $35/week after working part-time and paying his expenses. These two formulas show his weekly savings:

    f(1) = 35, f(n) = f(1) + f(n-1) for n > 1
    f(n) = 35n
        Which one of these formulas show the sequence written recursively and which shows it written explicitly? Justify your explanations.
        Use the recursive formula to make a table of values for 1 ≤ n ≤ 5. Show your calculations. Explain what your table means.
        Use any formula of your choice to find f(40). Explain why you chose that method and what your answer means. Show your calculations.
        Given the sequence of numbers: 5, 6, 8, 11, 15, 20, 26, 33, 41,… Explain whether or not this sequence can be considered a function.

4th question only

anonymous · Answer

it can be considered a function because it has a pattern.

oleg3321 · Answer

so the answer would be "it  can be considered a function."

oleg3321 · Answer

is that correct @arzunoorali

anonymous · Answer

actually when i look at it again i dont think i would be a function because in order for it to be a function it has to have a patter like x+1?

anonymous · Answer

so i would scratch what i said before and say no it is not a function because it doesnt have a consistent pattern
