In mathematics, 1 + 2 + 4 + 8 + ⋯ is the infinite series whose terms are the successive powers of two. 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 to infinity, so the sum of this series is infinity.

Find the Sum of the Series 1+2+4+8 This is a geometric sequence since there is a common ratio between each term . In this case, multiplying the previous term in the sequence by gives the next term .
