Question

u3:04: unit 3 test
is the formula recursive, explicit, or neither?
next = now - 8, starting at 50

explicit

recursive

neither

Explanation:

A recursive formula defines a term in a sequence using previous terms. The given formula \( \text{NEXT} = \text{NOW} - 8 \) (starting at 50) defines the next term (\(\text{NEXT}\)) using the current term (\(\text{NOW}\)), which is characteristic of a recursive formula. An explicit formula defines a term directly in terms of its position \(n\), which is not the case here. So the formula is recursive.

Answer:

B. Recursive
