Webrepeatedly with the same N, one of the two values (2.5) will, with probability one, lead to long-run profits, the other to long-run losses. But which is which? The expected value of the game-the deciding factor-is 2-N( N ) N r(j), where 7T(-) is the periodic function whose first m values are the 7Tj. By itself, this representation tells us nothing. WebConsider an arithmetic progression (AP) whose first term is a 1 (or) a and the common difference is d.. The sum of first n terms of an arithmetic progression when the n th term is NOT known is S n = (n/2) [2a + (n - 1) d]; The sum of first n terms of an arithmetic progression when the n th term(a n) is known is S n = n/2[a 1 + a n]; Example: Mr. Kevin …
