Find the next three terms in the patter 9, 4, - 1, - 6, - 11 ... then describe the pattern

You can notice that each time you subtract 5

9-5=4

4-5=-1

-1-5=-6

-6-5=-11

following the same pattern, the next term would be:

-11-5 = - 16

this is a linearily decreasing pattern (decreases with constant linear rate)
