Can your search term occur more than once in the file? If so, what do you want to happen when a second instance is fewer than ten lines after the first? Is it possible that a "Findme" occurs on the last line of the file and if so, what do you want to happen then? For example:

This is line1
At line 2. Did you Findme 
This is line3
This is line4
this is another Findme embedded in line 5
This is line 6
this is line 7
this is line 8
Line 9: yet another findme
line 10
line 11
line 12
line 13
line 14
line 15
line 16
line 17
line 18
line 19 is the 10th line after the next-to-last instance of searchterm
line 20
line 21
and so on...
line 23
24: last Findme

IMO, you'll need no more than beginner skills to write a script (solution OR attempt-at-a-solution STILL left to the OP) that produces this output:

At line 2. Did you Findme
This is line3
This is line4
this is another Findme embedded in line 5
This is line 6
this is line 7
this is line 8
Line 9: yet another findme
line 10
line 11
line 12
line 13
line 14
line 15
line 16
line 17
line 18
line 19 is the 10th line after the next-to-last instance of searchterm
24: last Findme

...but whether or not this is comensurate with your "requirement" (job? homework? other?) depends on the answers to the questions posed above.
