The Nth term formula for oblong numbers is N = N(N+1)
It is: nth term = 35-9n
Tn = 1 + 3n
The nth term is: 5-6n
The given sequence is an arithmetic sequence with a common difference of 6. To find the nth term of this sequence, we can use the following formula: nth term = first term + (n - 1) x common difference where n is the position of the term we want to find. In this sequence, the first term is 1 and the common difference is 6. Substituting these values into the formula, we get: nth term = 1 + (n - 1) x 6 nth term = 1 + 6n - 6 nth term = 6n - 5 Therefore, the nth term of the sequence 1, 7, 13, 19 is given by the formula 6n - 5.
Formula for nth termTn = a + (4n - 1) {where a is the first term and n is natural number}
The given sequence is decreasing by 1 each time, starting from 9. Therefore, the nth term of this sequence can be represented by the formula ( a_n = 10 - n ), where ( a_n ) is the nth term and n represents the position in the sequence.
2(n-1)
(n^2+n)/2

The nth term is: 3n+1 and so the next number will be 16
This is an arithmetic sequence which starts at 14, a = 14, and with a common difference of -1, d = -1. We can use the nth term formula an = a + (n - 1)d to get an = 14 + (n - 1)(-1) = 14 - n + 1 = 15 - n.
