Answer = 2 - (-3) = 2 + 3 = 5 minus minus means plus.

"x" would equal 1 because 7/1 is 7 minus 2 equals 5 and 3/1 is 3 plus or + 2 is 5.

The answer is 1. 33 repeat

After long division, (2x2-5x+5)/(x-2) = 2x-1+3/(x-2).

The sequence follows this pattern: you square the number, then add 2 to the result, then subtract one from that result; then you repeat. If you check, you will see that 1 squared is 1; 1 plus 2 is 3; 3 minus 1 is 2; 2 squared is 4; 4 plus 2 is 6; 6 minus 1 is 5; and 5 squared is 25. So, the next term would probably be 25 plus 2, or 27.
