Answer:

The common difference between each term in the sequence is 3. To find the 21st term, we can use the formula for the nth term of an arithmetic sequence:

a_n = a_1 + (n - 1)d

where a_1 is the first term, d is the common difference, and n is the term number we want to find.

Substituting the given values, we get:

a_21 = 15 + (21 - 1)3

a_21 = 15 + 60

a_21 = 75

Therefore, the answer is (c) a^21=75.
