Answer 1

Given

Griffin purchased 42 one-ounce Krugerrand Gold Coins.

And, he set a goal of buying 5 Krugerrand Gold coins every year.

To find the recursive formula.

Explanation:

It is given that,

Griffin purchased 42 one-ounce Krugerrand Gold Coins.

And, he set a goal of buying 5 Krugerrand Gold coins every year.

That implies,

The first term is 42.

And, the increase in the sequence is 5.

That is, the common difference d is 5.

Therefore, the recursive formulas are,

$t_0=42,\text{ }t_{n+1}=t_n+5$
