Answer 1

We can recall that:

Arithmetic progression is a progression in which every term after the first is obtained by adding a constant value, called the common difference (d). So, to find the nth term of an arithmetic progression, we know $an=a1+(n-1)d.$ $a1$ is the first term, a1 + d is the second term, third term is $a1+2d,$ and so on.

The series follows the addition of two numbers and then multiply it by $2$

$3+6=9\times2=18\\5+3=8\times2=16\\8+2=10\times2=20\\4+6=10\times2=20$

Hence, the correct option is $(d).$
