The pattern is +2 /2 +3 /3 +4 /4, and the next term would be +5, or 8.
The next two numbers in the sequence are... 45 & 54.

The next number in this sequence is 13112221.

It is: 34
8 and then 1.6
My guess: 2.5
The next two numbers in the sequence are... 45 & 54.

The next number in the sequence 3-15-6-30-21 is -207.
The pattern in the sequence 3, 6, 12, 21 can be identified by examining the differences between consecutive terms: 6-3=3, 12-6=6, and 21-12=9. The differences (3, 6, 9) are increasing by 3 each time. Continuing this pattern, the next difference would be 12 (9 + 3). Therefore, the next number in the sequence is 21 + 12, which equals 33.
50. Fit the quadratic Un = 6.5n2 - 16.5n + 12
If the last number is 1/3 (it should be), the next number is 5 and 1/3
