square of (n x 2)
Formula for nth termTn = a + (4n - 1) {where a is the first term and n is natural number}
The nth term is (36 - 4n)
72/2n
(n+1)^2 Please tell me you know what that means.

36 Seems like: 1 4 9 16 25 is squared sequence: 1 2 3 4 5 So 6 squared will be 36.
(n+1)^2 Please tell me you know what that means.
You must mean what is the next number in the series, not the 'nth', which is undefined. The next number is 58.
For {12, 15, 18} each term is the previous term plus 3; a general formula for the nth term is given by t(n) = 3n + 9. For {12, 24, 36} each term is the previous term plus 12; a general formula for the nth term is given by t(n) = 12n.
T(n) = 9 x 2(n-1)
after -9 it is -15 then -21, -27 and the ninth is -36
12, 20, 28, 36, 44
