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. Conversely, it is possible to find a rule such that any number of your choice can be the next one. In this case, the simplest rule is Un = 36 - 3*n and so N = 21.
There are infinitely many possible answers. But the simplest is Un = 33 - 3n for n = 1, 2, 3, ...

The largest is 30. Let the largest of the four consecutive even numbers be n; then the four consecutive even numbers are (n - 6), (n - 4), (n - 2) & n, and: ((n - 6) + (n - 4) + (n - 2) + n) ÷ 4 = 27 ⇒ (4n - 12) ÷ 4 = 27 ⇒ n - 3 = 27 ⇒ n = 30
Call the unknown number n. From the problem statement, 5(6 + n) = 24, or 30 + 5n = 24, or 5n = 24 - 30 = - 6, or n = -(6/5).

The latitude of Kyiv, Ukraine is approximately 50.45° N, and the longitude is around 30.52° E.
5016. Here's how: Each term is 1 less than the terms in 9, 18, 27 ..., which is the sequence 9*N, with N = 1..33. So the actual formula for the sequence is {9*N - 1} The sequence 1,2,3...N can be summed by (N+1)*N/2 --> N=33: (33+1)*33/2 = 561, so the sum of the first 33 terms of 9+18+27+297 = 9*(1+2+3+..+33) = 9*561 = 5049. But our sequence terms are each one less than the terms in 9,18,27, so subtract 33 from 5049 = 5016.
