It could be: 2*214 = 428
77040
72
The pattern involves subtracting decreasing values from each number: 107 - 9 = 98, 98 - 8 = 90, 90 - 7 = 83, and 83 - 6 = 77. Following this pattern, the next subtraction would be 77 - 5, which equals 72. Therefore, the next number in the sequence is 72.
Each number is multiplied by an incrementing value. 107 is multiplied by 2, 214 is multiplied by 3, 642 is multiplied by 4 and so on.
119. un = (-n4 + 15n3 - 77n2 + 225n + 192)/6
77040
77,040

If the fourth term were 2568 there is a simple answer, but with the series going up and down, I have no clue.

Each number is multiplied by an incrementing value. 107 is multiplied by 2, 214 is multiplied by 3, 642 is multiplied by 4 and so on.
The next number is 77040. Solution: 107 x 2 = 214x 3 = 642 x 4 = 2568 x 5 = 12840 x 6 = 77040
119. un = (-n4 + 15n3 - 77n2 + 225n + 192)/6
77040. It goes like, 107 * 2 = 214 214 * 3 = 642 642 * 4 = 2568, and so on. x * a(+1) = (a new)x Except that the word "completes" would suggest that there are no more terms. Not true!
107 98 90 83 77 __ 68 65
9-2=7, 23-9=14, 51-23=28, 107-51=56. therefore, since the next number in the sequence will be twice the previous difference, it will be 107+112 which is 219
1 and 107 (107 is a prime number).
