Answer:
When the difference of two numbers is zero, it means that the two numbers are the same.
Therefore, any irrational number substracted by itself will be equal to zero.
Here some examples:
- √8 - √8 = 0
- √1.6 - √1.6 = 0
- π - π = 0
This is an aritmetic series;
a=-10
d=-7--10
d=3
n= 7
Sum=

(2a+(n-1)d)
Sum=

sum=3.5(-20+18)
sum=3.5(-2)
sum=-7
