According to Wittgenstein's Finite Rule Paradox every finite sequence of numbers can be a described in infinitely many ways and so can be continued any of these ways - some simple, some complicated but all equally valid. The simplest solution, based on Un = 4*(n + 2) for n = 1, 2, 3, ... is 32.
12 + (n - 1) x 4
Another Answer:- nth term = 4n+8 and so the next term will be 32

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, ...
8 + 4n
The nth term of the sequence is expressed by the formula 8n - 4.
n(n+1)
It is: nth term = 6n-4
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, ...
8 + 4n
The nth term of the sequence is expressed by the formula 8n - 4.
Given n and any number for the nth term, it is a simple matter to find a rule such that the above four numbers are the first four of a sequence and the given number in the nth position.However, the simple answer for simple questions is Un = 4n
28 - 8n
20-9x=n
n(n+1)
Un = 29 - 9n
It is: nth term = 6n-4
The nth term of the sequence -4 4 12 20 29 is 8n+12 because each time the sequence is adding 8 which is where the 8n comes from. Then you take 8 away from -4 and because a - and - equal a + the answer is 12. Which is where the 12 comes from. Hope I helped.
The nth term of this sequence is 3n + 4
Divide the sequence by 5 and the answer becomes very obvious: 1, 4, 9, 16,...N2 So, 5, 20, 45, 80,...5N2
