Question 1158457: given the first term and the common difference of an arithmetic sequence, find explicit rule and the 37th term

You DO NOT NEED "find" explicit rule for the general term of an arithmetic progression:
+------------------------------------------+
| You must know it, as you know 2x2 = 4. |
+------------------------------------------+
= + (n-1)*d.
In your case, = -32 + (37-1)*20.
You do arithmetic.
Do the next exercise by the same way.
