see the image i have provided......
key point - "arrange in descending order"
let me explain it to you.
(i) F is smallest so i kept it at last
(ii) C - E = 1 means C is greater than E by 1 so i put them together.
(iii) according to this point, F is in the mid of A and D. and A is smaller. so A is after F and D is before F.
(iv)Bis after D and before F.
