Question

find the nth pattern of 3, 9, 15, 21, 27, ...

Answer 1

this is an arithmetic series with common difference 6

nth term = a + (n-1)d
= 3 + ( n - 1) 6
= 6n - 3

Answer 2

is that what you require kiko? - i wasn't sure what you mean by nth pattern

Answer 3

an = 3(2n-1)

an = 3(4n)2

an = 9n - 6

an = 12n - 9

ur answer is correct but which of this one is correct? this are answers for that question

Answer 4

the first one is the same as mine - if you distribute the 3 you get 6n - 3
