You are doubling the values each time. So it is U{n} = 2ⁿ⁻¹ for n = 1, 2, 3, 4.
------------------------------------
Nothing can be said about values of U{n} beyond n = 4, as that above is only one of infinitely many functions which give the values {1, 2, 4, 8} for n = {1, 2, 3, 4}. For example:
In the above formula, U{5} = 16
But if U{n} = (27n⁴ - 266n³ + 933n² - 1318n + 648)/24
then U{1..4} are also {1, 2, 4, 8}, but U{5} = 42

1 4 9 16 25 36 what is the rule for this pattern?
It is increasing by odd numbers consecutively._______or: n = the term number, the rule is: n2 or n(n). 12=1(1x1=1), 22=4(2x2=4), 32=9(3x3=9), and so on.
What is the pattern rule for 1 2 4 8 16 32 64 128?
Every number is double the previous number, where the first number is 1.
What is the pattern rule for 4 5 7 11 19?
One rule for this pattern is to add twice the previous value added 4 + 1 = 5 5 + 2×1 = 5 + 2 = 7 7 + 2×2 = 7 + 4 = 11 11 + 2×4 = 11 + 8 = 19 Continuing the next numbers would be: 19 + 2×8 = 19 + 16 = 35 35 + 2×16 = 35 + 32 = 67 ...
What is the pattern rule for this pattern 1-2-4-7-11-16?
