Mathematics Enhanced Sample Scope and Sequence

The number of triples in each set that are not in red represents the n t h number in the summation. Thus, there will be n =49- x new triples added to the previous amount of triples. As x decreases by 1, n increases by 1, thus adding the next number in th e summation to the previous total = ∑ i =0 n i . ................
