Answer 2

Answer:

$\boxed{70}$

Step-by-step explanation:

Given pattern :

7 , 16 , 34 , ? , 142 , 286 .

Let ? be a variable name it x .

Let us group the data into 2 elements each :

7 , 16

16 , 34

34 , x

x , 142

142 , 286 .

Focus on 7 , 16 .

Here square logic won't work , neither subtraction or multiplication.

Only thing is to add 7 + 9 = 16

Next 16 + 18 = 34

So we are basically adding the next multiple of 9 .

34 + 27 = 51

But 51 + 36 = 87 so we have to reject the logic.

Try with multiply and add.

7 , 16

7 × 2 + 2 = 16

16 × 2 + 2 = 34

This logic seems nice.

Lets verify with 142

142 ×2 + 2 = 286 indeed .

So 34 × 2 + 2 = x

= > x  = 68 + 2 = 70

70 should be the value .
