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 in the sequence is 122. The pattern involves adding increasing increments to each number in the sequence: +14, +10, +11, +13.
107 double difference each time 2 + 7 = 9 9 + 7 + 7 = 23 23 + 14 + 14 = 51 51 + 28 + 28 = 107

The next number is 77040. Solution: 107 x 2 = 214x 3 = 642 x 4 = 2568 x 5 = 12840 x 6 = 77040
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!

1 and 107 (107 is a prime number).
107 double difference each time 2 + 7 = 9 9 + 7 + 7 = 23 23 + 14 + 14 = 51 51 + 28 + 28 = 107
n1 = 3n2 = 3(3) + 2 = 9 + 2 = 11n3 = 3(11) +2 = 33 + 2 = 35n4 = 3(35) + 2 = 105 + 2 = 107The fourth term in the sequence (n4) is 107.
