Sequences and Series SERIES • A series is the expression that results when the terms of a sequence are added together. • Summation notation is the notation for a series that represents the sum of the terms. Also known as sigma notation (Greek letter ∑)
Sequences and Series • In the series i is the index of summation 1 is the lower limit of summation 4 is the upper limit of summation
Sequences and Series • Write the series using summation notation: • 4 + 7 + 10 + 13 + … + 46 • 7 + 14 + 21 + … + 77 • -4 – 8 – 12 – 16 - …
