The explicit rule for given sequence is:

Further explanation:
We have to determine first of all if the sequence is arithmetic or geometric.
- If the difference of two consecutive terms is same then the sequence is arithmetic sequence
- If the ratio of two consecutive terms is same then the sequence is geometric sequence
Given sequence is:
12,22,32,42

The common difference is 10 which is same for all consecutive terms. So the sequence is an arithmetic sequence.
The general formula for arithmetic sequence is:

Putting the values of a1 and d

Awnser:
You can fit up to 64 cubes in the rectangular prism.
Step-by-step explanation:
Well, we know that each side measures 4 inch each.
So, 4(L) x 4(W) x 4(H) = 64.
