Answer 2

Step-by-step explanation:

Even numbers from 1 to 250 will be 125 as there r equal even and odd numbers

so n=125 AP:2,4,6,8.....

so a=2, d=1 to find S125

s

$s = \frac{n}{2} (2a + (n - 1)d) \\ s = \frac{125}{2} (2(2) + 124 \times 1) \\ s = \frac{125}{2} (4 + 124) \\ s = \frac{125}{2} (128) \\ s = 125 \times 64 \\ s = 8000$
