75The number which best completes the sequence 10 30 15 16 48 24 25 is 75.
What number best completes the sequence 1 1/2 5 10 1/2 18
The number which best completes the sequence below is:2 9 5 13 10 19 17?
It is: 10-3 = 7
that best completes the sequence 2 9 5 13 10 19 17 is 27.
27. But that continues the sequence, it does not complete it.

To find the missing number in the sequence 10, 15, 28, we can look for a pattern in the differences between the numbers. The difference between 10 and 15 is 5, and the difference between 15 and 28 is 13. If we assume a pattern in the differences, the missing number could be 21, which fits as the average of 15 and 28. Thus, the sequence could be 10, 15, 21, 28.
The sequence appears to alternate between adding and subtracting numbers. The pattern seems to be +11, -7, +5, -2, +6. Following this pattern, the next number in the sequence would be +3 from the previous number, which would be 21.
The given sequence appears to be composed of perfect squares: (1^2 = 1), (4^2 = 16), (10^2 = 100), and (13^2 = 169). The missing number corresponds to (7^2 = 49), which fits the sequence of perfect squares. Thus, the missing number is 49.
