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, ...
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...
-1,-2,+2,-4,+4,-5,+5, +0. the sequence is subtract twice, add once, subtract again, add, then subtract, then add twice.
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
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
10
They are in alphabetical order.
-2,-4,-6.
The next number in the sequence is 62. The difference is doubling each time. 6-2=4 : 14-6=8 etc...
