Step-by-step explanation:

You have to fix them properly first, only then will we  understand.

Even Numbers are integers that are exactly divisible by 2, whereas an odd number cannot be exactly divided by 2.

638+50 = 688 = 6+8+8 = 22 => 2+2 => 4 even

288+50 = 338 = 3+3+8 = 12 => 1+2 =>3 odd

468+50 = 518 = 5+1+8 = 14 => 1+4 => 5 odd

736+50 = 786 = 7+8+6 = 21 => 2+1 => 3 odd

548+50 = 598 = 5+9+8 = 22 => 2+2 => 4 even

420+50 = 470 = 4+7+0 = 11 => 1+1 => 2 even
