I have the following problem which might seem simple.
I would be happy if you could help me with it.

There is a list of values such as..

100.20
100.23
100.35
122.45
122.55
122.67
122.75
145.88
145.97
146.01
146.10
etc.

As you can see some of the values are close to each other those values that are close to each other have to be grouped into groups so that the difference of a values to the average value is not greater then a value X.
For example: X=0.15

group1: Average:100.26
100.20 dif=0.06
100.23 dif=0.03
100.35 dif=0.09

group2: Average:122.60
122.56 dif=0.04
122.67 dif=0.03
122.74 dif=0.14

Outlier: 122.43 since dif=0.17>X

group3: Average:145.99
145.88 dif=0.11
145.97 dif=0.02
146.01 dif=0.02
146.10 dif=0.11

Thank you for any help that you could give me with this.
