Given that,

The arithmetic sequence is
a_n=17+6(n-1)

To find,

The first four terms of the sequence.

Solution,

a_n=17+6(n-1)

Put n = 1

$a_2=17+6(1-1)\\\\=17$

Put n = 2

$a_2=17+6(2-1)\\\\=23$

Put n = 3

$a_3=17+6(3-1)\\\\=29$

Put n = 4

$a_4=17+6(4-1)\\\\=35$

Hence, first four terms are 17, 23,29,35.
