Create list of values for start and end value of range given specific interval

Hi all,

I'd appreciate any help to gerenate a list of value based on specific interval and maximum values like below:

Interval=10
Max Value = 69

A1=1
A2=10
A3=11
A4=20
A5=21
A6=30
.
A13=61
A14=69

If the Interval is changed to 7 then the list of value will become
A1=1
A2=7
A3=8
A4=14
.
A19=64
A20=69

Thanks in advance.

Thanks sweep,

It is works for me.
