It is: nth term = 7n-9
The nth term is 5n-3 and so the next term will be 22
The nth term is 2n2. (One way to find that is to notice at all the numbers are even, then divide them by 2. The sequence becomes 1, 4, 9, 16, 25, which are the square numbers in order.)
The nth term is 7n-5 and so the 6th term will be 37
2(n-1)
n - 1
If the nth term is 8 -2n then the 1st four terms are 6, 4, 2, 0 and -32 is the 20th term number
t(n) = n(n - 3)
It is: nth term = -4n+14
This is the Fibonacci sequence, where the number is the sum of the two preceding numbers. The nth term is the (n-1)th term added to (n-2)th term
(n2+n+2) / 2, starting with n=0.
The nth term is (2n - 12).
It is: nth term = 7n-9
Well, darling, the nth term for the sequence 18, 12, 6, 0, -6 is -6n + 24. So, if you plug in n = 1, you get 18; n = 2 gives you 12, and so on. Just a little math magic for you to enjoy!
The Nth term in the series is [ 2N ] .
The nth term of the sequence is (n + 1)2 + 2.
The nth term is 5n-3 and so the next term will be 22
