Select the number that can replace the question mark (?) in the following series.

Question 15:Â Which number will replace the question mark (?) in the following series?
1, 2, 6, 24, 120, ?

a)Â 240

b)Â 570

c)Â 720

d)Â 360

here the given pattern is 325, 259. 204, 160, 127, 105, ?

and so let the missing number be y

here we can see that

259 – 325 = -66

204 – 259 = -55

160 – 204 = -44

127 – 160 = -33

105 – 127 = -22

here we can see that every time the difference is reducing by -11

so , y – 105 = -11

y = 94

here we need to find the wrong number in 12439, 23549, 34659, 45769

as we will add the digits of every number

12439 : 1+2+3+4+9 = 19

23549 : 2+3+5+4+9 = 23

34659 : 3+4+6+5+9 = 27

45769 : 4+5+7+6+9 = 31

As we can see that in very case the sum of digits of number is a prime number except in case of 34659 and hence 34659 is the odd one out

consider the first column

here add 5 + 6 + 2$\times$ 9 = 29

now consider the last column

here add 3 + 7 +2$\times$ 8 = 18

following the same pattern

we get 1+x+2$\times$ 9 = 22

x + 19 = 22

x = 3

8 $\times$ 1 = 8

8Â $\times$ 2 = 16

16 $\times$ 3 = 48

48 $\times$ 4 = 192

So, the answer would be option b)192.
