N=0inf n/2 n is the expected number of consecutive times you'll get the same outcome when you repeatedly flip a coin Since there's two equally likely options, you'd expect a run to last for two flips Aside from that (because intuition can't always be relied upon and one can't know everything), you can apply the same trick as beforeQuestion Four algebra 2 questions for practice before a test??Popular Problems Algebra Identify the Sequence 2 , 4 , 8 , 16 , 32 2 2 , 4 4 , 8 8 , 16 16 , 32 32 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 2 2 gives the next term In other words, an = a1 ⋅rn−1 a n = a 1 ⋅ r n 1
