Use Gauss's approach to find the following sums (do not use formulas).

a. 1 + 2 + 3 + 4 +...+ 102

b. 1 + 3 + 5 + 7 +...+1001

a. The sum of the sequence is ?

My answer 102-51(103)= 5,253

b. The sum of the sequence is?

My answer 500.3(1,002)=501,300.6

Are my answers correct? If not why, and how do I get the correct answers?
