B Correct answer
Explanation

This is an arithmetic progression with a = 30 and d = 4. The 27th term = a + (n-1)d = 30 + (26 * 4) = 30 + 104 = 134.

AI explanation

This sequence follows an arithmetic progression where the first term a is 30 and the common difference d is 4. Using the arithmetic progression formula for the nth term, Tn = a + (n - 1)d, we substitute the values to find the 27th term: 30 + (27 - 1) * 4. Calculating 26 times 4 gives 104, and adding 30 results in 134.
