It is 4n+5 and so the next term will be 25
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
n'th term: n^2 + 5
There are infinitely many possible answers. Given ANY number, it is always possible to find a polynomial of order 5 [at most] that can be used as the nth term rule for the given five number and the additional sixth. There are also non-polynomial solutions. Each different sixth number will result in a different polynomial and, since there are infinitely many sixth numbers, there are infinitely many answers to the question. Having said that, the simplest polynomial solution is Un = 9n - 2
The Nth term formula for oblong numbers is N = N(N+1)
There is no formula for prime numbers. They form a random sequence.
The nth hexagonal number is given by the formula: hn = 2n * (2n - 1) / 2
There is no such formula. Rectangular numbers are composite numbers and there is no known formula that will generate either composite numbers or prime numbers.
the first 4 terms of the sequence which has the nth term is a sequence of numbers that that goe together eg. 8,12,16,20,24 the nth term would be 4n+4
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.
It is: nth term = 35-9n
At least two or more numbers are needed to work out the nth term
The nth term of the sequence is expressed by the formula 8n - 4.
nth term = 5 +8n
The nth term is: 5-6n
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, ...
