This sequence is the result of 3 functions one after the other. These functions are:
squared, add 2, minus 1.
So 1 squared = 1, +2 = 3, -1 = 2, squared = 4, +2 = 6, -1 = 5, squared = 25....
So the next step would be +2 to get 27, then minus 1 to get 26.
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
1 1 3 2 4 6 5 25 25 27 26
26
The sequence is not a finite one so it cannot be completed.
26. ---- 24. ---- 27. ---- 25. ---- 28. ----
The sequence appears to be an infinite one. If that is the case, it cannot be completed; it can only be continued.
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.
Nothing "completes" the sequence because it goes on forever - without end.
