starting with n=1,
cannot be (C)
Try (B)
3(1)+5=8, and terms increase by 3

1th term ( n = 1 ) :
3 n + 5 = 3 * 1 + 5 = 3 + 5 = 8
2th term ( n = 2 ) :
3 n + 5 = 3 * 2 + 5 = 6 + 5 = 11
3th term ( n = 3 ) :
3 n + 5 = 3 * 3 + 5 = 9 + 5 = 14
4th term ( n = 4 ) :
3 n + 5 = 3 * 4 + 5 = 12 + 5 = 17
8 , 11 , 14 , 17
Answer B
