Sum It Up
An arithmetic sequence can be written in sequence notation using the function an = a1 + d(n − 1).
A geometric sequence can be written in sequence notation using the function an = a1 • rn−1.
A geometric series is a sum of a list of numbers with a common ratio. The sum of a series is determined by the function Sn =
a1(rn)−a1/r-1
Sigma notation can be used to find the sum of a sequence with a given number of terms. The Greek symbol Σ can be used with a lower index and upper index to indicate which terms of the sequence to add together.

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
