n³+3

Write the first four terms using the nth term above.

I dont even know where to start..

And then theres these:

Draw lines to match each nth term rule to its number sequence:

TERMSNumber sequences

4n 4,7,12,19

(n+1)² 4,8,12,16

n²+3 4,9,16,25

n(n+3) 4,10,18,28

I dont know how to work out which ones match... (There not in the right order at the moment)

HELP PLEASE
