Answer with explanation:
The given statement is which we have to prove by the principal of Mathematical Induction

1.→For, n=1
L H S =2
R H S=1
2>1
L H S> R H S
So,the Statement is true for , n=1.
2.⇒Let the statement is true for, n=k.

---------------------------------------(1)
3⇒Now, we will prove that the mathematical statement is true for, n=k+1.

Hence it is true for, n=k+1.
So,we have proved the statement with the help of mathematical Induction, which is

All of the answer choices except B would be correct for this problem.
If you use the common denominator of .5 for both sides of the ratio, you will arrive at 3:5 as a simplified form.
