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: 5n+3 and so the next term is 28
It is: 10n-7 and so the next term is 43
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 sequence 3, 8, 13, 18, 23, 28 increases by 5 each time. This indicates a linear pattern. The nth term can be expressed as ( a_n = 3 + 5(n - 1) ), which simplifies to ( a_n = 5n - 2 ). Thus, the nth term of the sequence is ( 5n - 2 ).
The nth term is: 5-2n
x2-3=n
2n + 1
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
20 - (3 * (n - 1))
