a)19
b)21
c)23
d)25

Answer 1

Answer:

d. 25

Step-by-step explanation: 11+2=13, 13+2+2=17, 17+2+2+2=25, 25+2+2+2+2=41, 41+2+2+2+2+2=73

Answer 2

25 will be the answer for that number series.

Given:

The number series 11,13,17,_,41,73.

To Find:

We have to find the missing number for that number series.

Solution:

This is a problem for the series.

Let us tackle the problem

We can easily solve the problem as follows.

Let us assume that the missing number of the given series is x.

We can easily see that,

$11+2^{0}=11$

$11+2^{1} = 13$

$13+2^{2} =17$

......

$41+2^{5} = 73$

and so on.

Therefore,

$17+2^{3} =25$

$25+2^{4} =41$

Hence, the answer for that number series is 25.
