Weddle's Rule

Let the values of a function f(x) be tabulated at points x_i equally spaced by h=x_(i+1)-x_i, so f_1=f(x_1), f_2=f(x_2), .... Then Weddle's rule approximating the integral of f(x) is given by the Newton-Cotes-like formula

int_(x_1)^(x_7)f(x)dx=3/(10)h(f_1+5f_2+f_3+6f_4+f_5+5f_6+f_7).
