The missing number is 21.

The reason is because you are adding seven and then subtracting one. You start out with 3 (3 + 7 = 10) then (10 - 1 = 9) then (9 + 7 = 16) and so on.

It is 15 in base 10.

The solution depends on how many numbers are missing and where they were. If there is only one, If it is between 4 and -5 then -0.5 If it is between -5 and -10 then -8 If it is between -10 and -16 then -13 Of course, the answer would be different if there were more than one number missing.

The median of a single number, such as 15915161681110, is itself.

10 30 15 16 48 24 25 75...

18, 23, 10, 39, 22, 17, 16, 15 Mean = (18 + 23 + 10 + 39 + 22 + 17 + 16 + 15)/8 = 20 Lowest Number in set is 10 Highest Number in set is 39 Range = (39 - 10) = 29

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

The number 249 in hexadecimal would be F9. The digits in base 16 correspond to powers of 16 rather than 10. For a two-digit number, the place values are 16 and 1, and the usable values are from 0 to 15, with values 10 through 15 represented by letters A (10) through F (15). F9 = (15x16) + (9x1) = 240 + 9

The missing number is 34. The progressive difference between the numbers doubles: 4 + 2 = 6 6 + 4 = 10 10 + 8 = 18 18 + 16 = 34 34 + 32 = 66
