What is the sum of the first six terms of the geometric series?
2-6+18-54+

-40?

Step-by-step explanation:

2-6+18-54 = -4+18-54 = 14-54 = -40

Sn = - 364

Step-by-step explanation:

Sn = a(r^n - 1)/(r-1)

=2(-3^6 - 1)/(-3-1)

= - 364

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.

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
