[] F-BF.2 Write arithmetic and geometric sequences both recursively and with an explicit formula, use them to model situations, and translate between the two forms.鈽匒-SSE.4 Derive the formula for the sum of a finite geometric series (when the common ratio is not 1), and use the ...
A series is the sum of the terms in a sequence, so an arithmetic series is the sum of the terms in an arithmetic sequence. Let S represent the sum: S=a_1+a_2+a_3++a_(n-2)+a_(n-1)+a_n. Write the sum again, except write the terms from last term to first term: S=a_...
