Answer:
For a=0.9876 and b=0.9887 mid point will be 0.98815
Explanation:
We have given a = 0.9876 and b = 0.9887
And N = 2
We have to find the mid point
For finding mid point we know that formula
Midpoint
, here we have given a=0.9876 and b = 0.9887
So midpoint will be

So for a=0.9876 and b=0.9887 mid point will be 0.98815
