What is the formula for finding the nth term of an arithmetic sequence?

• an = ak + (n + k)d

• an = ak + d(n - k)

• an = ak + nd

• an = ak + (n - k)

What is the common difference in an arithmetic sequence?

• A constant value added or subtracted to each term to get the next term.

• The product of all the terms in the sequence.

• A random value added or subtracted to each term to get the next term.

• The sum of all the terms in the sequence.
