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
t(n) = n(n - 3)
The pattern for the sequence 0 0 1 3 6 is that each term is obtained by adding the previous term multiplied by its position in the sequence (starting from 1). In other words, the nth term is given by n*(n-1)/2.
-1
the (n-1)th term plus the (n-2)th term.
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.
2n^2-1
The nth term of the sequence is (n + 1)2 + 2.
The differences are 3, 5, 7, 9,11, ... and the first term is -1; the nth term is: n² - 2
An = 2(n - 1)2 + 2(n - 1) = 2n(n - 1)
The nth term in this arithmetic sequence is an=26+(n-1)(-8).
The nth term is: 3n-7 and so the next number will be 11
The nth term is: 3n-7 and so the next number will be 11
the nth term of the sequence 98, 94, 88, 80 can be expressed as 98 - (n - 1) * 2.
If the nth term is 8 -2n then the 1st four terms are 6, 4, 2, 0 and -32 is the 20th term number
