To create a mod counter using flip flops that counts from 5 down to 2 and repeats this cycle...example 5, 4, 3, 2, 5, 4, 3, 2, 5, 4, 3, 2....

3. The attempt at a solution

I currently can get it to count from 7 down to 2 no problems...the issue is...I dont know how to skip states 7 and 6 right now. Using 3 jk flip flops...allows 2^3 states...or 0-7. Once the state reaches 1...I use an and gate to clear all the flip flops so that it jumps back to 7. Here is my schematic so far...but I'm assuming I have to somehow manipulate the j and k inputs to skip states 7 and 6; basically not hardwire a 1 to j and k. Any help would be appreciated...thanks.
