In the given number series which follows the definite rules then find out the value of (M, N, O, and P) in second number series.

7  18  42  94  204

4   M   N    O     P

What value will come in place of P?

A) 179 B) 184
C) 164 D) 156
 
Answer & Explanation Answer: D) 156

Explanation:

Here the given series 7  18  42  94  204 follows a pattern that, 

7

×2+4 = 18

18 ×2+6 = 42

42 ×2+10 = 94

94 ×2+16 = 204

Similarly,

4

×2+4 = 12

12 ×2+6 = 30

30 ×2+10 = 70

70 ×2+16 = 156

Hence, the value of P = 156.

A) 3 B) 2
C) 1 D) 0
 
Answer & Explanation Answer: D) 0

Explanation:

Let assume the value of a,b &c that will satisfy the equation.
so a=1,b=1,c= -1 or a=1,b= -1 &c=1 or a= -1,b=1,c=1
here all three cases satisfy the equation
assume any one a=1,b=1,c= -1

Hence (a+b)(b+c)(c+a)=(1+1)(1-1)(-1+1) = 0
