1/4 + 1/16 + 1/64 + 1/256 + ⋯. Archimedes' figure with a = 3 4. In mathematics, the infinite series 1 4 + 1 16 + 1 64 + 1 256 + ⋯ is an example of one of the first infinite series to be summed in the history of mathematics; it was used by Archimedes circa 250–200 BC. [1] As it is a geometric series with first term 1 4 and common ratio 1 4 ...
The geometric series on the real line. In mathematics, the infinite series 1 2 + 1 4 + 1 8 + 1 16 + ··· is an elementary example of a geometric series that converges absolutely. The sum of the series is 1. In summation notation, this may be expressed as. The series is related to philosophical questions considered in antiquity, particularly ...
Ranma ½: Rock-Scissors-Puzzle (Ranma ½: Ougi Jaanken) A puzzle game based on rock, paper, scissors. Hands are dropped showing the rock, paper, and scissor signs and are used to remove other hands that have the opposite sign. Its Japanese name is composed of ougi (meaning secret) and jaanken, a play on the word janken (the Japanese name for ...
From then to March 1, anyone who played the game on Linux would receive a free Tux penguin, which can be equipped in-game. Team Fortress 2 was announced in March 2013 to be the first game to officially support the Oculus Rift, a consumer-grade virtual reality headset. A patch was made to the client to include a "VR Mode" that can be used with ...

1 + 1 + 1 + 1 + ⋯ is a divergent series, meaning that its sequence of partial sums does not converge to a limit in the real numbers . The sequence 1 n can be thought of as a geometric series with the common ratio 1. For some other divergent geometric series, including Grandi's series with ratio −1, and the series 1 + 2 + 4 + 8 + ⋯ with ...
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. However, it can be manipulated to yield a number of ...
1 − 2 + 4 − 8 + ⋯. 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.
