Ta có:
$$B = \frac{1}{2} + \left(\frac{1}{2}\right)^2 + \left(\frac{1}{2}\right)^3 + \dots + \left(\frac{1}{2}\right)^{99}$$Nhân đôi hai vế:
$$2B = 1 + \frac{1}{2} + \left(\frac{1}{2}\right)^2 + \dots + \left(\frac{1}{2}\right)^{98}$$Trừ theo vế:
$$2B - B = 1 - \left(\frac{1}{2}\right)^{99}$$$$B = 1 - \left(\frac{1}{2}\right)^{99}$$Vì $\left(\frac{1}{2}\right)^{99} > 0 \Rightarrow B < 1$ (Đpcm).
