Answer: The correct option is (C) 44.
Step-by-step explanation: We are given to find the 15-th term of the sequence using the following formula for the n-th term of the sequence:

Since we are to find the 15-th term of the given sequence, so we will substitute the value of n as 15 in the given formula.
Substituting n = 15 in the given formula (i), we get

Thus, the 15-th term of the given sequence is 44.
Option (C) is correct.
