In the problem description they assign an index of 1 to B = 2 and they want to know how many dots are in the n-th pattern. T(n) = (n+1)(n+2)/2 = number of dots in the n-th pattern. Negative n makes no sense, so answer is pattern n = 61. This is a triangle with 62 dots in the base and 62(62+1)/2 = 1953 total dots.5/5
