To find the missing term in the given sequence, we need to observe the pattern or rule that governs the sequence.
Looking at the sequence, we can see that the difference between consecutive terms is increasing by 1 each time. The difference between the terms is as follows:
0 - (-1) = 1
3 - 0 = 3
8 - 3 = 5
15 - 8 = 7
24 - 15 = 9
35 - 24 = 11
48 - 35 = 13
63 - 48 = 15
80 - 63 = 17
From this pattern, we can deduce that the difference between consecutive terms follows the pattern of increasing odd numbers.
To find the missing term, we need to continue this pattern. The next difference would be 17 + 2 = 19. Hence, the next term after 80 would be 80 + 19 = 99.
Therefore, the correct answer is B) 99.
