3 and then there are other possible functional relationships.
There is only one polynomial of degree 3 and that is
Un= (2n3- 15n2+ 19n + 12)/3 where n = 1, 2, 3, ...
Consider the sequence: 2, 4, 6, 8, 10. The pattern in this sequence is that each term increases by 2 from the previous term. This is an example of an arithmetic sequence where the common difference is 2. The next term would be 12, continuing the pattern.
The answer for the number that follows the sequence 4-6-3-7-9-6-10 is 12. The pattern is +2,-3,+4,+2,-3,+4,.....,+2,-3,+4,...
The missing numbers in the sequence 2 3 4 6 are 5 and 7.
18. The pattern is 3+1=4, 4+2=6, 6+3=9, 9+4=13, so 13+5=18
18 b/c the pattern is +1,+2,+3...
Consider the sequence: 2, 4, 6, 8, 10. The pattern in this sequence is that each term increases by 2 from the previous term. This is an example of an arithmetic sequence where the common difference is 2. The next term would be 12, continuing the pattern.
The odd one out in the sequence 2, 4, 6, 8, 10, 12 is 10. The pattern in the sequence is that each number is increasing by 2, except for 10, which breaks the pattern. The other numbers in the sequence follow a consistent pattern of increasing by 2, making 10 the odd one out.
The answer for the number that follows the sequence 4-6-3-7-9-6-10 is 12. The pattern is +2,-3,+4,+2,-3,+4,.....,+2,-3,+4,...
The missing numbers in the sequence 2 3 4 6 are 5 and 7.
18. The pattern is 3+1=4, 4+2=6, 6+3=9, 9+4=13, so 13+5=18
The pattern follows a sequence of triangular numbers. Each number in the sequence is derived by adding consecutive integers: 1 (1), 1 + 2 (3), 1 + 2 + 3 (6), 1 + 2 + 3 + 4 (10), and so on. Therefore, the next number in the sequence can be found by adding 5 to the previous number, resulting in 21 + 6 = 28.
18 b/c the pattern is +1,+2,+3...
-1,-2,+2,-4,+4,-5,+5, +0. the sequence is subtract twice, add once, subtract again, add, then subtract, then add twice.
The modes are 2, 3, 4, 5 and 6.
42, each number in the sequence is the addition of the previous two: 2-2-4-6-10-16-26 2+2=4 4+6=10 6+10=16 10+16=26 16+26=42
