The differences are 3, 5, 7, 9,11, ... and the first term is -1; the nth term is: n² - 2
It is: nth term = -4n+14
3n-2
It is: nth term = 6n-4
3n - 1
The nth term would be -2n+14 nth terms: 1 2 3 4 Sequence:12 10 8 6 This sequence has a difference of -2 Therefore it would become -2n. Replace n with 1 and you would get -2. To get to the first term you have to add 14. Therefore the sequence becomes -2n+14. To check your answer replace n with 2, 3 or 4. You will still obtain the number in the sequence that corresponds to the nth term. :)
The nth term is 2 + 3n.
The nth term is 3n+2 and so the next number will be 17
They are: nth term = 6n-4 and the 14th term is 80
It is: 26-8n
2n^2-1
The nth term of the sequence is (n + 1)2 + 2.
