Diagram of simple filtration: oversize particles in the feed cannot pass through the lattice structure of the filter, while fluid and small particles pass through, becoming filtrate.
An odd function can be identified by replacing both the x and y values with -x and -y values. If the values in your equation are the opposite (positives are negatives and negatives are positives), then the function is odd. Take, for example, this equation y = x^2.
Notice that this sum is always odd. Each of the consecutive numbers can be represented as (n+m)/2, where m is an odd number that ranges from -2k+1 to 2k-1. That is, P even (k,n)=(n-2k+1)/2 (n-2k+3)/2 ...otice that this sum is always odd.
