C Correct answer
Explanation

The given sequence is an arithmetic progression with a first term of 8 and a common difference of 3. Using the formula for the n-th term, a_n = a + (n - 1)d, the 27th term is calculated as 8 + (27 - 1) * 3 = 86.

AI explanation

The given sequence is an arithmetic progression with the first term a equal to 8 and a common difference d equal to 3. Using the formula for the nth term, Tn = a + (n - 1)d, we substitute the values to get T27 = 8 + (27 - 1) times 3. This simplifies to 8 + 78, which equals 86. The 27th term is 86.
