The answer depends on where, in the sequence, the missing number is meant to go.
Furthermore, whatever number you choose and wherever in the sequence it is meant to be, it is always possible to find a polynomial of degree 5 that will go through all five points given in the question and your chosen one.
Using a polynomial of degree 4, the next number is 213.
The rule is
Un = (103n4 - 1242n3 + 5201n2 - 8670n + 4680)/24 for n = 1, 2, 3, ...

Find the missing number in the series (in red) :2 , 4 , 5, 9, 9 , 16 , 14 , ? , 20 , ….
20
To find the next number in the series 4, 8, 12, 20, we need to identify the pattern or rule governing the sequence. In this case, the pattern is that each number is the sum of the previous two numbers. 4 + 8 = 12, 8 + 12 = 20, and 12 + 20 = 32. Therefore, the next number in the series is 32.

the rule is plus 4 divided by 3 plus 4 divided by two==========================================Answer #2:The missing number is 8. It belongs between 24 and 12 .The rule is: Add 4, divide by 3, rinse and repeat.

Don't know about the number but 'missing' is misspelled
32 The rule is to add 3n, where n is the number of the number in the series. (add 3, 6, 9, 12).
