\(k = 2 + 4 + 6 + ... + 100\)
\(k = \frac{50}{2} (2+100) = 2550\)
\(m = 1 + 3 + 5 + ... + 99\)
\(m = \frac{50}{2} (1+99) = 2500\)
\(k - m = 2550 - 2500 = 50\)
Answer \(50\)
\(k = \frac{50}{2} (2+100) = 2550\)
\(m = 1 + 3 + 5 + ... + 99\)
\(m = \frac{50}{2} (1+99) = 2500\)
\(k - m = 2550 - 2500 = 50\)
