You mentioned
, so we should first of all consider what is the difference between each term i.e whether it is a set of consecutive integers or consecutive odd integers or consecutive even integers or consecutive integers with larger/smaller differences. Next you mentionHow many terms
, so we should know the difference between each term is one. So if we move on from -18 with increments of 1 towards 33, we should generally consider 0 as part of the set. So IMO: 0 should be considered while counting the given set of consecutive integers. Also I would like to know if anyone has any other views on this one.in the set of consecutive integers

Don't even think about the zero. Just use the formula to calculate the number of terms in a set: (x-y)+1
33-(-18)+1=33+18+1=52
33-(-18)+1=33+18+1=52
I don't know what to say, really. Three minutes to the biggest battle of our professional lives. You find out life's this game of inches, so is football. Because in either game - life or football - the margin for error is so small. I mean, one half a step too late or too early and you don't quite make it. One half second too slow, too fast and you don't quite catch it. I'll tell you this, in any fight it's the guy whose willing to die whose gonna win that inch. That's football guys, that's all it is. Now, what are you gonna do?
