The simplest polynomial, of an infinite number of possible solutions, is
Un = (-2n3 + 12n2 - 7n + 6)/3
Un = 5n - 2
The nth term is 2 + 3n.
The nth term is 4n - 3
It is: 10n-7 and so the next term is 43
It is: 5n+3 and so the next term is 28
The nth term of a sequence is the general formula for a sequence. The nth term of this particular sequence would be n+3. This is because each step in the sequence is plus 3 higher than the previous step.
The nth term is: 5-2n
Nth term With the nth term you substitute the n for the term number (e.g. 50) so the 50th term in 2n+3 would be 2x50+3=103
x2-3=n
2n + 1
20 - (3 * (n - 1))
The given sequence is an arithmetic sequence with a common difference of 4 between each term. To find the nth term of an arithmetic sequence, we use the formula: nth term = a + (n-1)d, where a is the first term, d is the common difference, and n is the term number. In this case, the first term (a) is -3, the common difference (d) is 4, and the term number (n) is the position in the sequence. So, the nth term of the given sequence is -3 + (n-1)4 = 4n - 7.
