Explanation / Answer

Question 7:

Answer : A power set is a set of all the subsets of a set.

So the answer is option ' B '.

Question 8 :

Answer :

In the given series we can clearly observe that ,

in each term the denominator value is 1 greater the numerator.

The first numerator term is 1 and last numerator term is 50.

There are 50 terms in the series , so we can sum up and can be written in sigma form like the option ' D '.

So the option is ' D '.

Question 9 :

Answer :

In the given recurrence relation if we put n = 2, then the equation becomes

a2 = 3a1 + 4a0

Given a0 = 2 and a1 = 3

then a2 = 3*3 + 4*2

a2 = 17

In the given options if we put n=2, option ' A ' is only giving the value of a2 = 17. So the answer is option ' A '.
