If the first term of an arithmetic sequence is -4, and the 12th term is 20, find the common difference and the sum of the first 12 terms.
First express the nth term, then solve for 'd', and apply the sum formula.
A sequence starts from 2, and the sum of the first 'n' terms is equal to the sum of an arithmetic series whose first term is 2 and common difference is 3. If 'n' is 10, find the required sum.
