Use the geometric series formulas to find the sum of the geometric series.
1 − x + x2 − x3 + ⋯ + x30 in terms of x

The sum of the geometric progression is .

Step-by-step explanation:

Given data in the question:-      

We have to find the sum of Geometric Progression.

Solution:-      

As we know the sum of geometric progression is

Where r is the common ratio defined as

n(no of terms)=31

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
