If x0 = xn = 0 and if xk = 15, then the series will be: 0, 3, 6, 9, 12, 15,...theachiever wrote:In the sequence x0,x1,x2,x3.......xn each term from x1 to xk is 3 greater than the previous term,and each term from xk+1 to xn is 3 less than the previous term,where n and k are positive integers and k<n.
