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

Question

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

Clearly the first number is 1, and last number is 1001, and the increment is 2. This a plug n chug.

yes but, i will have to use a formula that way -

3*+2+2/-2^2

Answer 1

1+3+5+...+2009
