Question
Find a general term, $a_{n},$ for each sequence. More than one answer may be possible.$$1 \cdot 3,2 \cdot 4,3 \cdot 5,4 \cdot 6, \dots$$
Step 1
We can see that the first number in each term is increasing by 1 each time (1, 2, 3, 4, ...). This suggests that the first part of our general term will involve $n$. Show more…
