Question

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
Part 1: Which one of these formulas show the sequence written rercursively and which shows it written explicity? Justify your explanantions.
Part 2: Use the recursive formula to make a table of values for 1 ≤ n ≤ 5. Show your calculations.
n Calculations Answer (f(n))
1
35n
2
3
4
f(1)=5 ; f(n)= f(n-1) + (n-1) for n>1
5
Part 3: Use the explicit formula to demonstrate the most direct method to find

Answer 4

A) The first is recursevly, since you need the past term(n-1) to find the next one(n)
