pi/2 is in the middle of those two number, because the middle of those numbers is 1.5707 and if we see is less than 3 so you have to make the square of 3 and it will give you another number that represents pi/2
I hope you understood me, because I don't even understood me, but is pi/2 trust me
It would be J. This is because the opposite of -3.5 would be 3.5 and the absolute value is just a positive integer or positive number so that would be 3.5 as well so its J
