What is the 4th term of the geometric sequence with
alt="a_{1}" align="absmiddle" class="latex-formula"> = 5 and ratio (multiplier) = -3?
1 answer:
<u>Answer:</u>
The 4th term of the geometric sequence with = 5 and ratio (multiplier) = -3 is -135
<u>Solution:</u>
Given that, first term a of a G.P = 5 and common ratio ( r ) = -3 for an geometric progression.
We have to find the 4th term of the above given geometric progression
We know that, nth term of an G.P is given by

So, now, 4th term is


hence, the 4th term of the given G.P is -135

<u>Distance Between two Points in the Plane</u>
Given two points A(x,y) and B(w,z), the distance between them is:

We are given the points (5, 14) and (−3, −9). Substituting into the formula:




Answer:
x=32
Step-by-step explanation:
Multiply both sides by 4.
(x/4)*(4) = (8)*(4)
