The simplest is Un = 2n + 1
prime numbers
3 + 3 + 5 = 11 3 + 3 + 7 = 13 3 + 5 + 7 = 15 3 + 3 + 11 = 17 3 + 5 + 11 = 19 3 + 7 + 11 = 21 3 + 7 + 13 = 23 3 + 11 + 11 = 25 5 + 11 + 11 = 27 7 + 11 + 11 = 29
The median of 2 3 5 7 11 is 5, the central number.
With U{n} = (4n⁵ - 57n⁴ + 306n³ - 759n² + 890n - 336)/24U{1, ..., 5} = {2, 3, 5, 7, 11}U{6} = 42However, I think the rule your teacher wants you to give is it is a list of the prime numbers, so it continues: 13, 17, 19, 23, 29, ...
3/7, 3/9, 3/11, 5/11
prime numbers
3 + 3 + 5 = 11 3 + 3 + 7 = 13 3 + 5 + 7 = 15 3 + 3 + 11 = 17 3 + 5 + 11 = 19 3 + 7 + 11 = 21 3 + 7 + 13 = 23 3 + 11 + 11 = 25 5 + 11 + 11 = 27 7 + 11 + 11 = 29
The rule is t(n) = 5 + 2*n, where n = 1, 2, 3, ...
Un = 4n - 13.
(5/11) / (3/7) = (5/11) * (7/3) = (5*7) / (11*3) = 35 / 33
The median of 5, 7, 11, 14, 8, 7, 11, 3, 0, and 7 is 7.
5t - 7 = 11 5t - 7 + 7 = 11 + 7 5t = 18 5t/5 = 18/5 t = 18/5 t = 3 3/5
The average or mean of 3, 5, 7, 9, and 11 is 7.
The median of 2 3 5 7 11 is 5, the central number.

7/(5*9*3*11)
It is: (7+3)*(11-5) = 60
