Multiple choice general knowledge math & puzzles Try... 8 , 54 , 192 , … 400 500 450 490 Reveal answer Fill a bubble to check yourself B Correct answer Explanation The pattern is $n imes n^3$ or similar: $1 imes 2^3 = 8$, $2 imes 3^3 = 54$, $3 imes 4^3 = 192$. The next term is $4 imes 5^3 = 4 imes 125 = 500$. This follows the sequence $n(n+1)^3$ for $n=1, 2, 3, 4$.
