A recursive pattern is a sequence of numbers that entails a pattern between succeeding numbers. in this case, we can see that sequence 2 has an arithmetic difference of 9, that is the proceeding terms are 40, 49, 58.. The third one has also an arithmetic difference that is increasing by 3 each. The answer then is A which has no pattern.
Yes they are entirely contained
You go up 4 times and go to the left 2 times so the slope would be 4/-2
Just do 198 divide by 33. The answer is how much gas will be used.
