Up to which step is the process reversible?

Directions: In the following illustration, an input is given followed by steps performed on it. Carefully observe the changes and find the pattern and answer the questions given in the new input.

Input:- 2 5 7 6 8 9 1

Step 1:- 5 26 50 37 65 82 2
Step 2:- 8 23 53 34 68 79 5
Step 3:- 18 48 108 70 138 160 12
Step 4:- 13 22 58 47 73 78 70
Step 5:- 31 70 166 117 211 238 22
Step 6:- 100 205 282 327 448 259

Step 6 is the last step and the output

Now according to the above steps, solve this input.

Input:- 3 3 4 5 6 2 8

Input: 3 3 4 5 6 2 8 Step 1: 10 10 17 26 37 5 65 Step 2: 13 7 20 23 40 2 68 Step 3: 28 16 42 48 82 6 138 Step 4: 18 6 25 22 45 1 73 Step 5: 46 22 67 70 127 7 211 Step 6: 67 88 136 196 133 217 Following calculations are done while arranging the input: Step 1 = Input(square) + 1 every element Step 2 = Step 1 + 3, Step 1 – 3 alternately Step 3 = 2(Step 2 + 1) Step 4 = Step 3 - Step 1 Step 5 = Step 4 + Step 3 Step 6 = 1^st + 2^nd element of Step 5, 2^nd + 3^rd element of Step 5, 3^rd + 4^th element of Step 5 and so on and only 6 elements in Step 6. This is the correct option because this is the last step which is reversible.
