According to Wittgenstein's Finite Rule Paradox every finite sequence of numbers can be a described in infinitely many ways - some simple, some complicated but all equally valid. One possible rule isT(n) = (2*n4 - 16*n3 + 52*n2 - 68*n + 33) for n = 1, 2, 3, ...
Another is U(n) = 3n for n = 1, 2, 3, ...

The nth term is found by multiplying the first term by the common ratio to the n minus one power.

In this case, that turns out to be 3 x 3^n-1

What is the nth term for 1 7 13 19?

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.
