B Correct answer
Explanation

Pattern: 64*0.5+2=34, 34*1+2=36, 36*1.5+2=56, 56*2+2=114, 114*2.5+2=287, 287*3+2=863. The term 860 is incorrect.

AI explanation

The pattern multiplies by 0.5, then adds 1, multiplies by 1.5, adds 2, multiplies by 2.5, adds 3, and so forth. Continuing from 114, multiplying by 3.5 gives 399, and adding 4 gives 403. Therefore, 860 is the incorrect number in the series.
