 ## Instructions
 
-Write a function which takes a list of integers, and which returns the (possibly empty) list of pairs of successive consecutive integers that there may be in the list.
+Write a function which takes a list of integers, and which returns the list of of successive consecutive integers that there may be in the list.

-```txt
-7
-1
-2
-5
-3

-
-### Output
-
-```txt
-1, 2
-3, 4

+First input, is the number of consecutive numbers needed to consider it as "consecutive", the second input is the list of integers.
 
 ## Examples
 
 See the `test` folder for examples of input/output.
