This sequence appears to be generated by adding the previous two numbers to get the next number. Starting with 2 and 6, we get 2 + 6 = 8. Then, 6 + 8 = 14, 8 + 14 = 22, and 14 + 22 = 36. This pattern follows the Fibonacci sequence, where each number is the sum of the two preceding ones.
There are many possible answers. One of these is Un = (79n6 - 2421n5 + 28225n4 - 159375n3 + 453736n2 - 606804n - 281520)/360 for n = 1, 2, 3, ...
Find a number that can be divided into both 28 and 36. If for example you try the number 2, you get:28/36 = 14/18.Both 14 and 18 can be divided by 2 as well, so repeat:14/18 = 7/9.7 and 9 have no more divisors in common, so there's your answer.(You could also have saved a step by noticing that both 28 and 36 are divisible by 4.)
I'm guessing your sequence is 1, 3, 6, 10, 15, ... In which case it continues: 21, 28, 36, 45, 55, 66, ... (These are the triangular numbers.)
28*36*63=63504
The next number in the sequence is 20. This is because the sequence is decreasing by 2, then decreasing by 6, then decreasing by 2, and then decreasing by 6. So, the next step would be to decrease by 2 again, resulting in the number 20.

The LCM is 252.
Yes it is. In sequence from 1, the first 10 triangular numbers are... 1, 3, 6, 10, 15, 21, 28, 36, 45 & 55.

12The next number in the sequence is the previous # divided by 3. So, 324/3 = 108; 108/3 = 36; 36/3 = 12
The nth term is (36 - 4n)
The number 36 is larger. It is 8 larger than 28.
