How do you do this question?

(-½, ½)

Step-by-step explanation:

r = -2x.  The geometric series converges when -1 < r < 1.

-1 < -2x < 1

½ > x > -½

The interval of convergence is (-½, ½).

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
