## How to check consecutive numbers

Hello mates!

I have one doubt.

I have this Excel:

So, I want to know if I don't have consecutive numbers.

Something like, if row number is row number - last row number = 1, it's ok. If it's 2, we have a not consecutive number.

Numbers are examples, I could have some message like "Not consecutive!" or something like that.

Is there any way to do this?

Just cheking if column has consecutive numbers and knowing where is the "jump".

Thank you so much! 🙂

@JaviF Correct, so you would substitute your consequetive number column for the date column. So, like the following:

``````Column =
VAR __Current = [ConsequetiveNumberColumn]
VAR __Previous = MAXX(FILTER('Table','Table'[ConsequetiveNumberColumn] < EARLIER('Table'[ConsequetiveNumberColumn])),[ConsequetiveNumberColumn])
RETURN
__Current - __Previous

``````

@JaviF See my article on Mean Time Between Failure (MTBF) which uses EARLIER: http://community.powerbi.com/t5/Community-Blog/Mean-Time-Between-Failure-MTBF-and-Power-BI/ba-p/3395....
The basic pattern is:
Column =
VAR __Current = [Value]
VAR __PreviousDate = MAXX(FILTER('Table','Table'[Date] < EARLIER('Table'[Date])),[Date])

VAR __Previous = MAXX(FILTER('Table',[Date]=__PreviousDate),[Value])
RETURN
__Current - __Previous

Thanks for your answer.

I don't have any Date column... Just the "consecutive" numbers.

How could I adapt the DAX to my problem?

Thanks again!

Thanks @Greg_Deckler 🙂

It seems that didn't work:

Var current and EARLIER don't work 😞

First one, the var says that 'Cannot find name' and it exists 100%.

The other one, 'Parameter is not the correct type'.

Any idea to solve these?

Thanks! 😄
