2(n-1)
> since the value rises by nine at each step and the first term is 12 the formula for > the nth term is: 12+(n-1)*9 Which simplifies to Sn = 9n + 3
It is: nth term = 29-7n
n-squared, or n to the power 2
The nth term is 4n-1 and so the next term will be 19
Formula for nth termTn = a + (4n - 1) {where a is the first term and n is natural number}
The Nth term formula for oblong numbers is N = N(N+1)
Tn = 1 + 3n
The nth term is: 5-6n
The nth term is: 3n+1 and so the next number will be 16
2(n-1)
(n+1)^2 Please tell me you know what that means.
The nth term is n2.
5n+1
If 3 is the first term, then the nth term is [ 3 x 2(n-1) ] .
9 3 1
n2
