c) 17
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.
This sequence is an interlace of two sequences: 13,17,21,25,29,33,..(each number 4 higher than the previous one) and 10, 15, 25,30,35(each number 5 more than the previous one). So the sequence continues 30,29,35,33,...

The sequence interval is 2 4 6 8 ( this is the difference of number). so the missing number is -1 if I'm not mistaken.

5+5 = 10 10+5 = 15 15-5 = 15 10+5 = 15

the answer should be 5
75The number which best completes the sequence 10 30 15 16 48 24 25 is 75.

10 The sequence is given by xn = 60/n
The sequence has the formula is 3x - 1 2 → 6 - 1 = 5 5 →15 - 1 = 14 14 →42 -1 = 41 41 → 123 - 1 = 122 The missing number is therefore 41.
