I cannot write the correct answer with my keyboard.*Originally posted by mwmiller***: 06 : 68 : 88 : -- : 98 :**

These numbers follow a specific sequence.

The colons are only used as a seperator. They do not represent a math function.

Each number has two digits.

One of the digits of the missing number isn't exactly a number.*Originally posted by mwmiller***: 06 : 68 : 88 : -- : 98 :**

These are just examples and are not the answer.*Originally posted by joe shmo***Sorry, that was a bad explanation. The number has actual numerical digits as it's read, but it's use in interpreting the pattern only has one "actual" digit. Right?**

It has two actual digits, such as 53 or 42. It is a two-digit number. - 03 Oct '15 12:30 / 1 edit

I would argue that 78 is the answer. Not 87. If that can't be recognized as a valid point, then I would say the neither answer is fully correct.*Originally posted by mwmiller***These are just examples and are not the answer.**

The original string of numbers are presented upside-down.

If you invert the entire string you will see that 87 is the correct missing number in the sequence. - 03 Oct '15 18:16

But you should also notice that as you read the string from left to right, all the inversions are numbers themselves. Not a regular number and an inverted number.*Originally posted by mwmiller***78 is not correct.**

We were supposed to be looking for a "number" that fills the gap in the sequence if you put 87 as the answer the original sequence reads*Originally posted by joe shmo***But you should also notice that as you read the string from left to right, all the inversions are numbers themselves.

06,68,88,L8,98
