Question

An anchor chain has 32 links lying on a ship's deck, while the rest of the chain is below deck height. Each time the raise-anchor control is activated, 9 more links come over the edge to lie on the deck.

Write a NEXT-NOW equation to model the number of chain links on the deck after n activations of the raise-anchor control.

Answer 1

Explanation:

Sounds like an arithmetic sequence, with first term being 32 and increment 9. The nth term will then be a(n) = 32 + 9(n - 1)
