I am sorry, It seems I made a mistake as I wanted to just remove my upvote until the case Sum[ar[j], {j, 4, h}] - Sum[ar[j], {j, 5, h}] worked but it seems that doing that I also removed a point as the score went from 6 to 4. The system stops me from upvoting now untill there is an edit but I will upvote if I see an edit . Sorry about that.

I think one of the reasons that the above example did not work is that sumRule1 does not seem to work with Sum[ar[j], {j, 4, h}] - Sum[ar[j], {j, 5, h}] although sumRule1 simplifies when the minus is inside of the sum as in Sum[ar[j], {j, 4, h}] + Sum[-ar[j], {j, 5, h}]

I could not get sumRule1 to simplify Sum[2*ar[j] + br[j], {j, 4, h}] - 2*Sum[ar[j], {j, 3, h}] + Sum[-br[j], {j, 5, h}]
