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.
27
25
Sn = 3n2 + 2n - 8
The number which best completes the sequence below is:1 1 3 2 4 6 5 25 ?
23
27.
The common terms in the two sequences are 21 and 466. Therefore, the number of common terms is 2.
You can use sequences ending in every number from 3 to 25 so 23 times.
480 = 25*3*5
25
The nth term is 6n+1 and so the next term will be 31
The best choice for the next term after those shown is 75 .We have no way to know whether or not that will 'complete' the sequence.
22
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,...
