Let us break down the series in groups of three numbers
38, 1368, 54758
89. 7743, 704702
67, 4355, ???
In the first group, we observe that
1368 / 38 = 36 , 54758 / 38 = 1441 , 36 x ( 38-36) + 1 = 1441 - 1368
In the second group,
7743/ 89 = 87 , 704702 / 89 = 7918, 87 x (89-87) + 1 = 7918 - 7743
Therefore , in the third group, we can work it out as follows:
4355 / 67 = 65
Then, 65 x (67 - 65) + 1 = 131 and 4355 + 131 = 4486
Finally,
4486 x 67 = 300562
The answer is 300562
