The number which best completes the sequence below is:1 1 3 2 4 6 5 25 ?
25
What number best completes the sequence 1 1/2 5 10 1/2 18

27.
The sequence is not a finite one so it cannot be completed.
26. ---- 24. ---- 27. ---- 25. ---- 28. ----
This sequence appears to follow the relation *3, /2 , +1, *3, /2, +1,........ By applying the above relation to the existing numbers we see that 24 + 1 = 25. Hence we apply the *3 logic to 25. We obtain 25 * 3 = 75 as the next number in the sequence.
The next number in the sequence is 27. To get the next number, double the number and add one. Except for the second number, all the numbers in the sequence follow this rule.
243
25 is the next number that appears in that sequence.
