There are many possible answers because there are many ways of generating the sequence.
One such is the cubic equation,
Un = (4n3 - 19n2 + 33n - 16)/2 for n = 1, 2, 3, ...
So U5 = 87.
96
5
The rule is: "To get the next term, double this term and subtract 2."(66 x 2) - 2 = 130 comes next
The differences between the pairs of numbers up to that point are 31, 32, 33, 34. If the difference between the fifth number and the sixth number is equal to 35, that would make the next number equal to 122 + 243 = 265.
33 and a half
The next number would be 95. You're adding square numbers in sequence to the previous number. 18+16 (42) = 34. 34+25 (52) = 59. Therefore 59+36 (62) = 95.
34
The next number will be 13+21 = 34
34, 55, 89, 144 is a portion of the Fibonacci sequence. The next number is 89 + 144 which is 233.

Fibonacci sequence adds the previous two numbers to get the next number. 1,1,2,3,5,8,13,21,34,55,89,144,233,377,610,987,1597
34, then 55, then 89, then 144, 223, 376, 599, 975, 1574
The rule is: "To get the next term, double this term and subtract 2."(66 x 2) - 2 = 130 comes next
The next number is 34 Thus: 3 1 4 2 6 4 10 8 18 16 34 (Note: 3 + 1 = 4 : 4 + 2 = 6 : and so on)
34 55 89 etc..
XXXIV or 34
