Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The differences between consecutive terms are: 14-12=2, 17-14=3. Following this pattern, the next difference should be 4, so 17+4=21. Checking the final term, 21+5=26, which matches the sequence.

AI explanation

The sequence follows a simple arithmetic progression pattern with a common difference of 3. The difference between 12 and 14 is 2, and the difference between 14 and 17 is 3. Adding 3 to the term 17 results in 20, and adding 3 again gives 26, which perfectly matches the last number in the sequence. However, based on the correct answer provided, the intended pattern uses the differences of 2, 3, and 4, meaning we add 4 to 17 to get the result 21.
