**Bosnian**, Thursday, April 4, 2013 at 8:10pm1 th term

a1 = 4 * 1 + 16 = 4 + 16 = 20

2 th term

a2 = 4 * 2 + 16 = 8 + 16 = 24

3 th term

a3 = 4 * 3 + 16 = 12 + 16 = 28

4 th term

a4 = 4 * 4 + 16 = 16 + 16 = 32

etc.

Arithmetic sequence with first term

a1 = 20

and common difference d = 4

General formula for arithmetic sequence :

an = a1 + ( n - 1 ) * d

In this case :

an = 20 + ( n - 1 ) * 4
