To solve this sequence, let's examine the pattern between the given numbers: 0, 7, 26, 63, ?, 215.
If we look closely, we can see that each number in the sequence is obtained by raising the index of the term to the power of 3 and subtracting the result from the next perfect cube.
Let's break it down:
- The first term is 0, which is equal to 1^3 - 1.
- The second term is 7, which is equal to 2^3 - 1.
- The third term is 26, which is equal to 3^3 - 1.
- The fourth term is 63, which is equal to 4^3 - 1.
So, to find the missing term, we need to calculate 5^3 - 1.
Using this pattern, we can conclude that the missing term is 124.
Therefore, the correct answer is C) 124.
