ARITHMETIC SEQUENCE, SERIES, AND MEAN Flashcards
list of numbers that are linked by a rule
sequence
finite sequence
has first and last term
infinite sequence
has first term but no last term
series
defined as the sum of numbers in a sequence
arithmetic sequence
list of terms that has a constant difference between two consecutive terms
a sub n = a sub 1 + (n-1)d
formula for arithmetic sequence
arithmetic series
