Answer: $\bold{(D)\ a_n=52-5n}$

<u>Step-by-step explanation:</u>

The explicit rule for an arithmetic sequence is: $a_n=a_1+d(n-1)\quad \text{where}\ a_1\ \text{is the first term and d is the difference}$

In the given sequence {47, 42, 37, 32, ... }, the first term $(a_1)$ is 47 and the difference (d) is 42 - 47 = -5

$a_n=47-5(n-1)\\.\quad=47-5n+5\\.\quad=52-5n$

For the sequence you are subtracting 5 from it. Because 32 + 5 =37, 37+5 = 42,. 42+ 5 = 47. so you are subtracting 5 from it. so from the problem, it would be one of the last two.

<h3>What is problem solving?</h3>

It should be noted that problem-solving enables us to identify and exploit opportunities in the environment and exert control over the future.

In this case, problem solving skills and the problem-solving process are a critical part of daily life both as individuals and organizations

Also, good problem solving activities provide an entry point that allows all students to be working on the same problem.

In this case, the open-ended nature of problem solving allows high achieving students to extend the ideas involved to challenge their greater knowledge and understanding and problem solving develops mathematical power.
