I have been given a table with three values of a function at three different points. In my textbook, the Composite Simpson's Rule has a following form:
$I=\frac h6(f_0+4f_1+2f_2+4f_3+...+2f_{2n-2}+4f_{2n-1}+f_{2n})$
Can this formula be used if I do not have any 'even' values? Can I do the following? $I=\frac h6(f_0+4f_1+f_{2n})$
