2500 The sum of all even numbers up to 100 is just two times the sum of the first 50. [tex] {50}^{2} + 50 = 2550[/tex] Then we get the sum of all even and odd numbers to 100. [tex] \frac{ {100}^{2} + 100 }{2} = 5050[/tex] Then we subtract the first from the second. [tex]5050 - 2550 = 2500[/tex] Also can I please have brainiest?
