How create a formula to copy but have the row change by fixed number?

I need to extract data from worksheet called “KI” to another worksheet called “Summary”. So for the first reference I used this formula =’KI 2011′!L16 The next cell I need to reference =’KI 2011′!L23 I need to repeat this many times but the only change is the row number which ALWAYS increases by 7, so next reference would be =’KI 2011′!L30 and so on. Is there anyway to do this automatically with a formula so I don’t have to keep selecting the cells hit = then go to the KI worksheet select the cell and hit enter? It would save alot of time from having to do that over 100 times. Thank you.
