n3
The nth term of the sequence is (n + 1)2 + 2.
Willies
It is: 27-2n
The pattern for the nth term is n3. Therefore, the fourth term in the sequence is equal to 43 = 64.
A single number, such as 1521273339 does not define a sequence. There is no nth term for a signle number.
The nth term of the sequence is (n + 1)2 + 2.
Willies
There is no pattern
nth term is 8 - n. an = 8 - n, so the sequence is {7, 6, 5, 4, 3, 2,...} (this is a decreasing sequence since the successor term is smaller than the nth term). So, the sum of first six terms of the sequence is 27.

after -9 it is -15 then -21, -27 and the ninth is -36
The first four terms are 3 9 27 81 and 729 is the 6th term.
A sequence of squares: n to the nth power
5 to 7 is 27 to 17 is 1017 to 19 is 219 to 29 is 1029 to 31 is 2there fore following the pattern the nth term is 4131 to 41 is 10
There are infinitely many possible answers. But the simplest is Un = 33 - 3n for n = 1, 2, 3, ...
