Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In mathematics, 1 − 2 + 4 − 8 + … is the infinite series whose terms are the successive powers of two with alternating signs. As a geometric series, it is characterized by its first term, 1, and its common ratio, −2. As a series of real numbers it diverges, so in the usual sense it has no sum. In a much broader sense, the series has a generalized sum of ⅓.
