Explanation

The differences are: 10-4=6, 22-10=12, 40-22=18, 64-40=24, 84-64=20, 130-84=46. The pattern of differences should be 6, 12, 18, 24, 30, 36. Thus, 64+30 = 94 should be the next term, not 84.

AI explanation

The series follows a pattern where we subtract 6 and add multiples of 12 sequentially. The pattern is 10 minus 6 is 4, 22 minus 12 is 10, 40 minus 18 is 22, 64 minus 24 is 40, 94 minus 30 is 64, and 130 minus 36 is 94. Therefore, the number 84 is wrong and should be 94.
