Rationale: fit the function t(n) = (-2n4 + 41n3 - 253n2 + 604n + 120)/30
for n = 1, 3, 4, ... and then evaluate the value for n = 2.

1,3,2,4,3,5,4,6,5,7,6,8,7,9,8,10,9,11,10,12I didn't know which number you were looking for exactley so I wrote 20 numbers in the sequence. The part you provided is in bold, italicized font
20 Each time it divides by 2... 160/2=80; 80/2=40; 40/2=20
The sequence appears to be decreasing with varying intervals: 50 to 33 (17), 33 to 25 (8), 25 to 20 (5), 20 to 17 (3), 17 to 14 (3), 14 to 13 (1), and 13 to 11 (2). The differences between the numbers suggest that the next number decreases by 1 from 11, resulting in 10. Therefore, the next number in the sequence is 10.

In the sequence 271217, the missing numbers can be determined by analyzing the pattern of the numbers. By looking at the sequence closely, we can see that the missing numbers are 18, 19, and 20. This is because the sequence follows a pattern of increasing by 1 from the previous number. Therefore, the missing numbers after 17 would be 18, 19, and 20 to complete the sequence.

To determine the missing number in the sequence 20, 0.8, we need to identify the pattern. One possible pattern is that each number is being divided by 10. In this case, 0.8 divided by 10 equals 0.08. Therefore, the missing number would be 0.08.

This question cannot be answered for two main reasons. The first is that you have not specified where, in the sequence, the missing number is meant to be. Clearly that makes a difference.Suppose you assume the missing number is the last in the sequence, then any number that you choose can be the next number. It is easy to find a rule based on a polynomial of order 6 such that the first six numbers are as listed in the question followed by the chosen next number. There are also non-polynomial solutions. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one. The same applies, wherever in the sequence the missing number was meant to be.

To find the missing number in the sequence 32, 52, 74, 112, 135, we need to identify the pattern or rule governing the sequence. The differences between consecutive numbers are 20, 22, 38, and 23, respectively. The pattern is not immediately clear, but it appears that the differences are not following a simple arithmetic progression. One possible explanation could be that the differences are increasing by odd numbers (2, 16, 15), so the next difference could be 15. Adding 15 to the last number in the sequence (135) gives us 150 as a potential missing number.
Think it's 30...then 20
