Given: a = 1000, b = 1001, c = 1002
We need to find the value of a^2 + b^2 + c^2 - ab - bc - ca
Solution:
a^2 + b^2 + c^2 - ab - bc - ca can be written as:
1/2[(a-b)^2 + (b-c)^2 + (c-a)^2]
Substituting the values of a, b, c:
1/2[(1000-1001)^2 + (1001-1002)^2 + (1002-1000)^2]
= 1/2[1+1+4]
= 3
Therefore, the value of a^2 + b^2 + c^2 - ab - bc - ca is 3.
Hence, the correct option is (D) 3.
