If look for the pattern in these numbers, you can see that they follow a simple sequence in which each number is four more than the previous one. They are not multiples of four though, so they will have to be offset. In this case, that offset is two. This means that we can express this sequence as:

f(n) = 2 + 4n

assuming that 6 is the first term, with an "n" value of 1.

It is: 26-8n

The nth term in this sequence is 4n - 2.

The sequence has a difference of 10, so the nth term starts with 10n. Then to get to -8 from 10 you need to subtract 18. So the nth term is 10n - 18.

The nth term in this arithmetic sequence is an=26+(n-1)(-8).

t(n) = (-5n4 + 62n3 - 247n2 + 334n - 36)/6

It is: 25-7n

Un = 25 - 7n

If you mean: 6 12 18 24 then the nth term is 6n

If the term number is n, then the nth term is 10(n-1) +8.

The nth term of that series is (24 - 6n).

The nth term is 18 -3n and so the next term will be 3

The nth term is 7n-3 and so the next term will be 39

There are different ways to say it, but they all produce the same pattern:Start at 10 and count by twos.Start at 10 and count up, but don't say the odd numbers.The nth term of the sequence is ( 8 + 2n ).

Un = 5n - 2

The nth term of the sequence is (n + 1)2 + 2.

The nth term is: n^2 +2 and so the next number will be 38

tn = n2 + 9, n = 1,2,3,...

72/2n

The next term is 45 because the numbers are increasing by increments of 3 5 7 9 and then 11

7n - 3

2n^2

The 'n'th term is [ 13 + 5n ].

The 'n'th term is [ 13 + 5n ].

The 'n'th term is [ 13 + 5n ].
