Since 17 is a prime number and larger than 13, the answer is 17 . Problem 2: Geometry & Ratios
Define (a_1 = 3). Recurrence: (a_n = 2(a_{n-1} - 2)). Compute step-by-step: (a_2 = 2(3 - 2) = 2(1) = 2) (a_3 = 2(2 - 2) = 2(0) = 0) (a_4 = 2(0 - 2) = 2(-2) = -4) (a_5 = 2(-4 - 2) = 2(-6) = -12). Mathcounts National Sprint Round Problems And Solutions
