Using the counter of a for loop in command line parameter

Say I have (in psuedocode)
For i=1 to 10
tar cvfb /... 5*i /junk(i)
end

What I mean is that I want each successive for loop to have the block size parameter be 5 times the current counter. This isn't my actual code, just a stupid example...So the question is how do I descrive that parameter so that it uses the counter times five and have the /junk(i) be run as /junk1, /junk2, etc...?

__________________________________________________________________________________________________________________________________________________

NAME
continue - Skip to the next iteration of a loop SYNOPSIS
continue _________________________________________________________________ DESCRIPTION
This command is typically invoked inside the body of a looping command such as for or foreach or while. It returns a TCL_CONTINUE code, which causes a continue exception to occur. The exception causes the current script to be aborted out to the innermost containing loop command, which then continues with the next iteration of the loop. Catch exceptions are also handled in a few other situations, such as the catch command and the outermost scripts of procedure bodies. EXAMPLE
Print a line for each of the integers from 0 to 10 except 5: for {set x 0} {$x<10} {incr x} { if {$x == 5} { continue } puts "x is $x" } SEE ALSO
break(3tcl), for(3tcl), foreach(3tcl), return(3tcl), while(3tcl) KEYWORDS
continue, iteration, loop Tcl continue(3tcl)
