C Correct answer
Explanation

This sequence 3-1-4-1-5-9-2-6 represents the digits of pi (3.1415926...). The next digit after 6 is 5, making option C correct. Pi is approximately 3.1415926535, so after 3.1415926 comes 5.

AI explanation

The sequence 3-1-4-1-5-9-2-6 is simply the digits of pi (3.14159265...). The next digit after 3.1415926 is 5 (pi continues 3.14159265358979...), so the answer is 5. Option 1, 3, and 8 don't match the actual digit sequence of pi at that position; they're just plausible-looking distractors for anyone not recognizing the pi pattern. Recognizing famous constants (pi, e, Fibonacci) is a common trick in these number-sequence puzzles.
