Explanation

The pattern is: 9*1+1=10, 10*2-2=18, 18*3+3=57, 57*4-4=224, 224*5+5=1125.

AI explanation

The series follows a pattern of multiplying by increasing integers and then adding or subtracting a number. Specifically, the pattern is (9 x 1) + 1 = 10, then (10 x 2) - 2 = 18, and then (18 x 3) + 3 = 57. Following this logic, the next term is (57 x 4) - 4 = 224, which can be verified by the final term (224 x 5) + 5 = 1125. The result is 224.
