Which recursive formula can be used to generate the sequence below, where f(1) = 3 and n ≥ 1? 3, –6, 12, –24, 48, … a. f(n + 1) = –3 f(n ) b. f(n + 1) = 3 f(n ) c. f(n + 1) = –2 f(n ) d. f(n + 1) = 2 f(n)

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
