c) 17
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,...
5
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.
22
the answer should be 5

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

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.
