Multiple choice general knowledge math & puzzles Find the next 2,12,30,56,? 90 84 98 82 Reveal answer Fill a bubble to check yourself A Correct answer Explanation The sequence follows the pattern n^2 + n or n(n+1) for even integers: 1*2=2, 3*4=12, 5*6=30, 7*8=56. The next in the series is 9*10=90. Alternatively, the differences are 10, 18, 26 (increasing by 8), so the next difference is 34; 56+34=90.
