The nth hexagonal number is given by the formula:
hn = 2n * (2n - 1) / 2
Formula for nth termTn = a + (4n - 1) {where a is the first term and n is natural number}
The nth triangular number is 0.5*n*(n+1)
The Nth term formula for oblong numbers is N = N(N+1)
Fn = Fn-1 + Fn-2 And F0 = F1 = 1
Give the simple formula for the nth term of the following arithmetic sequence. Your answer will be of the form an + b.12, 16, 20, 24, 28, ...
it is 6n
No, it will be a formula, because "the nth term" means that you have not defined exactly which term it is. So, you make a formula which works for ANY term in the sequence.
V = n3
The nth formula is Un = 1422303846 for all n.
Formula for nth termTn = a + (4n - 1) {where a is the first term and n is natural number}
The nth triangular number is 0.5*n*(n+1)
a + (n-1)d = last number where a is the first number d is the common difference.
The Nth term formula for oblong numbers is N = N(N+1)
Fn = Fn-1 + Fn-2 And F0 = F1 = 1
It is: nth term = 35-9n
The Nth triangular number is calculated by: N(N + 1) -------- 2 Hope this is useful!
