Answer:
so easy and obvious dude
Step-by-step explanation:
We know what every year has 365 but once every four years has 366. We can simplify it by saying that every year has 365 and 1/4 days
Now, we just have to mulitiply

So we can say that 50 years have 18262 days and chance to 18263 (depends when we started counting)
Answer: 35
Step-by-step explanation:
The formula to find this is number of terms/2(first term+last term)
So, we have 7 terms, our first is -4 and our last is 14
7/2(-4+14)=35
2+2+9+0+8+1+2+3+4+5+6+7+8+9 is 66
