1) 7, 11, 17, 25, 35

2) 6, 12, 22, 36, 54

6) The nth term is T= n^2 +4n -1

7) The nth term is T= n^2 + 3n

8) The nth term is T= 2n^2 + 2n + 5

I‘ll try to do the others, I’ll write the solutions in the comments of my answer

24 divide by 6= 4
4 time 4=16 time 4=64
So then you subtract 64-4=60
And you add the 8
8+60=68
