Find the 14th term of geometric sequence 5,-10,20,...

Step-by-step explanation:

The formula for a geometric sequence is

where n is the position number in the sequence, a1 is the first number in the sequence, and r is the common ratio. For us,

n is 14, a1 is 5, and the common ratio (the number we multiply by each number to get to the next one in line) is -2.

and

and

so

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
