Hello, I know the method to unravel, but I am having trouble finding patterns. Any help with this problem? Suppose a function d is defined by the following recursive formula, where n is a positive integer. d(n) = d(n − 1) + 2n + 1, d(1) = 3 Use the unraveling method to get a closed-form formula for d(n)
