Problem 43016. Find the next Fibonacci number

In the sequence of Fibonacci numbers, every number is the sum of the two preceding ones:

1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, ...

The initial two numbers are generally chosen as [1, 1].

Given one or more integers n, find the next integer that is a Fibonacci number, for each of them.

Example 1:

n = 6;
out = 8;

Example 2:

n = [12 44 50];
out = [13 55 55];
