Solutions

Solution (6-10):
Sol. Different operations are applied on the numbers in every step.
Step I: Even number is divided by 2 and then subtracted by 2. Odd number is divided by 3 and then subtract by 3.
Step II: add 1st and 2nd no. (+), difference of 2nd and 3rd no. (-) and so on. This operation starts from left end and continues till the addition of 7th and 8th no. So, the sequence is: +, –, +, –, +, –, +.
Step III: Sum of all the digits of each number
Step IV: Odd Number is multiplied by 2, Even number is multiplied by 3.

Input: 105 164 333 584 222 489 176 267
Step I: 32 80 108 290 109 160 86 86
Step II: 112 28 398 181 269 74 172
Step III: 4 10 20 10 17 11 10
Step IV: 12 30 60 30 34 22 30
