You can observe that the difference between two consecutive numbers in the pattern is 9.

Common difference:

17 - 8 = 9

26 - 17 = 9

35 - 26 = 9

44 - 35 = 9



an = 8 + 9 * ( n - 1 ) = 8 + 9 n - 9 =

9 n - 1


n = 1

a1 = 9 * 1 - 1 = 9 - 1 = 8

n = 2

a2 = 9 * 2 - 1 = 18 - 1 = 17


n = 3

a3 = 9 * 3 - 1 = 27 - 1 = 26


n = 4

a4 = 9 * 4 - 1 = 36 - 1 = 35


n = 5

a5 = 9 * 5 - 1 = 45 - 1 = 44
