FP1.7.1 - Summation of simple finite series

Summation of simple finite series.; Students should be able to sum series such as n n n ∑r, ∑r2, ∑r(r2 + 2). r=1 r=1 r=1 The method of differences is not required.

Use fp1.7.1 - summation of simple finite series to connect the rule to the data and decision in the question.

This matters because fp1.7.1 - summation of simple finite series determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply fp1.7.1 - summation of simple finite series to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: FP1.7.1 - Summation of simple finite series is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
