A perfect square factor of each of the given number on the left will be matched as:
126 ---> 9
192 ---> 16
112 ---> 16
245 ---> 49
75 ---> 25
162 ---> 9
<h3>What is a Perfect Square?</h3>
- A perfect square can be described as a special number which can be squared.
- Squared numbers are numbers that are gotten by multiplying a number by itself.
- For example, square of 25 is 5 (5×5). This means that 25 is a perfect square.
<h3>What is a Factor of a Number?</h3>
- Factors of a number can divide the number with no remainder.
- For example, 5 is a factor of 25, because 25/5 = 5.
Therefore, a perfect square factor of each of the given number on the left will be matched as:
126 ---> 9
192 ---> 16
112 ---> 16
245 ---> 49
75 ---> 25
162 ---> 9

The sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r) in our case:
s(n)=3(1-4^n)/(1-4)
s(n)=-(1-4^n)
s(n)=(4^n)-1 and s=1023
(4^n)-1=1023
4^n=1024
n ln4=ln1024
n=(ln1024)/(ln4)
n=5
