finding patterns in sequence and the function 3,6,11,18

⚑ Flag

Usually the first thing you do when answering a question like this is to look at the difference of 2 numbers. If there is a pattern, its the easiest way to solve !So break it down and look at the differences of each 2 numbers.6-3=311-6=518-11=7You can see that these numbers differ by a sequence that goes up by 2 every time. Logistically, this means that you can assume that the next number in the sequence will have a difference of 9 between 18 and the next number, so add 9 and 18 to get your answer18+9 = 27So therefore the sequence of numbers will be:3, 6, 11, 18, 27With the pattern between them being it goes up by 2 every time.
