Explanation

The pattern is: 5*1+1=6, 6*2+2=14, 14*3+3=45, 45*4+4=184, 184*5+5=925. The number 920 is incorrect; it should be 925.

AI explanation

Multiply each number by an increasing integer and add one to find the next number. Following this rule, 5 multiplied by 1 plus 1 is 6, 6 multiplied by 2 plus 2 is 14, and 14 multiplied by 3 plus 3 is 45. Continuing, 45 multiplied by 4 plus 4 should equal 184, and 184 multiplied by 5 plus 5 gives 925 instead of 920. Therefore, 920 is the incorrect number in the series.
