What is It?
Series teasers are where you try to complete the sequence of a series of letters, numbers or objects.
What is the missing number?
5 90 53 __ 11286 11249 11823
HintThe first step of the rule is *18, followed by two more steps, then repeated.
The rule is *18, -37, and +574. Then, repeat it once more.
The number is 627.

|What's the point of subtracting 37 and then adding 574? Why not just add 537?|

|i thought is was lousy...but points for trying |

|This teaser is practically impossible. And not to be mean, but it is the least liked on the website. Maybe you could make it a little easier next time? I applaud you for submitting a hard teaser, though, something not many people do.|

|Ummmm... Part of the point of teasers is actually stretching your brain out and trying to think of the answer. I agree w/above posts, though: this is practically impossible! Really, if you submit a teaser like this, you should provide some more clues and then a way that you could solve it mathematically in the answer. If everyone made up teasers randomly like this one, this would be a really disappointing site. I suggest you try a little harder on your next teaser!|

|This teaser is completely random. |
There's no thought process at all.
In fact, it's the least popular teaser on the site!
Actually, I don't think it's THAT bad.

|I don't understand how 5*18 -37 +574 is 90? |

|^ It's a two-step sequence. So it works like this:|
x18 = 90
bit random, but definitely not impossible, and I quite liked how I was caught off guard by a standard mathematical sequence after all the other ones.

|Definitely not impossible, in act I found it pretty easy. A good attempt, but definitely not my favorite teaser.|

|horrible. not to be m,ean but it is the least popular teaser on this site. I can tell that there were more comments but they were all so insulting that they were removed. Also this is impossible to figure out. I mean who's gonna say "oh, I bet the answer is x18 -37 +574." It should at least be in math if it has to be on this site.|

|I love math, but i have to say that this is a boring teaser. As someone else said its a good attempt but maybe make it a little easier and perhaps turn it into a story.|

|Incidentally it happens to be the least popular on the site, but I think people are just downrating it for difficulty. There is a difference between FUN and DIFFICULT.|
