It could be odd numbers, it could be prime numbers.
In an arithmetic progression the difference between each term (except the first) and the one before is a constant. In a geometric progression, their ratio is a constant. That is, Arithmetic progression U(n) - U(n-1) = d, where d, the common difference, is a constant and n = 2, 3, 4, ... Equivalently, U(n) = U(n-1) + d = U(1) + (n-1)*d Geometric progression U(n) / U(n-1) = r, where r, the common ratio is a non-zero constant and n = 2, 3, 4, ... Equivalently, U(n) = U(n-1)*r = U(1)*r^(n-1).
It is a progression by threes: 12=0,15=1, so 18=2,21=3,24=4 and 27=5.
-4 is the first negative term. The progression is 24,20,16,12,8,4,0,-4,...

The nth term of the series is [ 4/2(n-1) ].
It is a progression by threes: 12=0,15=1, so 18=2,21=3,24=4 and 27=5.
