Answer:
first row you add 4 to get the next term. look at the difference in numbers.
second row the difference is 3 so you add 3 to get the next one.
3rd row the nth term is 3n so the one above would be 2n and the first /top nth term would just be n on its own - meaning one lot of it
4th row add 5 so 7-5= 2 being the 0th term. so just add 5 each time. so it would be 4n
bottom row the difference is 14 or to get that do 26-12
don't let it trick you out- after the third term it goes to the tenth so it would be best getting a piece of paper and working the whole of it out so u don't get confused
