14.

The first, third and fifth number are even numbers. 2, 8, 12

And the second, forth and sixth numbers are odd numbers. 7, 3, 9

1. y = c + 2x

<span>c1= 2 (and subsequent c= next number in the series) and x is in </span>reducing order:

2 + 2x3 = 8

8 + 2x2 = 12

12 + 2x1 = 14

2. u = a (+-) 2(v).

a1=7 (and subsequent a= next number in the series) and v is in increasing order.

7 - 2x2 = 3

3 + 2x3 = 9

9 - 2x4 = 1

<span>the subsequent number is an even number, so it should be 14</span>

The degree of suppression of emotions was rated on a scale of 1 to 10) and study the effects taking measurements.

These studies are usually randomized ie subjects are group by chance.

As opposed to observation studies, where the researchers only measures what was observed, seen or hear without any intervention on their parts.
