Answer 2

91 is the missing number in the given series

Step-by-step explanation:

Given :

3 5 15 41 ? 173

Solution :

The logic behind this is ,

Take the first number in the given series add the square of the first odd number respectively and then add 1

Let us take 3,

       $3+1^2+1 = 5$

Next step,

Take the next number in the series and add the square of the next odd number and then add 1  

next number is 5,

$5+3^2+1 = 15$

In the same way,

$41+7^2+1 = 41+49+1 =91$

Hence the answer is, 91

$3 + 1^2 + 1 = 3+1+1 = 5\\5 + 3^2 + 1 = 5+9+1 = 15\\15 + 5^2 + 1 = 15+25+1 = 41\\41 + 7^2 + 1 = 41+49+1 = 91\\91 + 9^2 + 1 = 91+81+1 = 173$
