### The number which best completes the sequence below is 10 30 15 16 48 24 25?

This probably repeats the following sequence - (second number) = (first number)*3 (third number) = (second number)/2 (fourth number) = (third number)+1 then repeat so the answer is 75 according to this logic. 10 10*3=30 30/2=15 15+1=16 16*3=48 48/2=24 24+1=25 25*3=75 after this point, the sequence is broken.

### What number best completes this sequence 10 30 15 16 48 24 25?

Well, the pattern is easy. First multiply the number by 3. (10x3=30). Divide that number by 2 (30/2=15). Add 1 to that number (15+1=16). This rule works with the other sequences so this is the rule. You just need to apply it: 10, 30, 15, 16, 48, 24, 25, 25x3=75 75/2=37.5 37.5+1=38.5 The next THREE are: 75, 37.5, 38.5

### Best completes the sequence 1 3 7?

There are two possibilities. The sequence is 1, 3, 7, 15, 31, 63..... The sequence is 1, 3, 7, 13, 21, 31...... It depends on whether the difference from one number to the next is doubled (i.e., 2, 4, 8, 16, 32, etc), or if two is simply added each time to arrive at the next stop in the sequence (i.e., 2, 4, 6, 8, 10, etc). There could also be other sequences, but there…

### What number is next in the sequence1 1 4 3 9 6 16 10 25 15?

This is actually two sequences staggered back and forth: 1 4 9 16 25 1 3 6 10 As you can see, the first sequence is a series of perfect squares, and the second sequence is a series with a rate of change that is increasing by increments of one. The next number in the original sequence will be from the second series, making it 10 + 5, or 15. The sequence as a whole…
