igor_vitrenko [27]

The series will be:

4+16+64+.......+2^{50}

Hence, Option A is the right answer

Step-by-step explanation:

The series can be fount out by putting the values of i in the expression written with the summation

The expression is:

2^{2i}

while i = 1 to 25

Putting i = 1

2^{2(1)}\\= 2^2\\= 4

Putting i = 2

2^{2(2)}\\= 2^4\\= 16

Putting i = 3

2^{2(3)}\\= 2^6\\= 64

....

Putting i = 25

2^{2(25)}\\= 2^{50}

The series will be:

4+16+64+.......+2^{50}

Hence, Option A is the right answer

— = —
4 x


Solve it?

[Cross Multiply]

3x= 108

X= 36

How to check it?

Reduce 27/36 and see if it equals 3/4

OR

Plug both into the calculator and both should come out with the same decimal. In this case it is 0.75
