Can someone please help me?

Answer 1

So first u have to find the nth term, here the nth term is : 6n-4
Then replace the n with term that u want so:
6(30) - 4
= 180-4
=176
So it's B

Answer 2

Hello,


`u_(1) =2\\ u_(2) =2+6\\ u_(3) =2+2*6\\ u_(4) =2+3*6\\ ...\\ u_(n) =2+(n-1)**6\\ u_(30) =2+29*6=176\\`

Answer B
