Best ResponseYou've already chosen the best response.0The first differences would be 3, 20, 38, 62. The second differences would be 12, 18, 23 and 30. The third difference would be 6 for all of them

Best ResponseYou've already chosen the best response.0That's funny. Both answers are correct. My answer was that the nth term was the sum of the first n odd natural numbers. So the first number is 1, the second is 1+3=4, the third is 1+3+5=9, the fourth is 1+3+5+7 = 16
