Two answers we would like to highlight. The first one is from Patrik Parlefjord:

Chat GPT gave the answer 8, after believing that the “i” was involved in the multiplication. But after I pointed it out the there was an input number to the loop, it changed its answer:
Starting at 1, after five doublings the final value is:
1 → 2 → 4 → 8 → 16 → 32
Hence, the indicator “result” will show 32 once the loop finishes.

Copilot was a bit confused about the “1.23” that was already in the result block, but correctly assumed that the numbers were unrelated to the multiplication.
However, it could not understand the loop at all, and came up with the answer 2. So again, I had to help it understand a bit more. I explained that the structure around the blocks is a “for-loop”, and that the arrows was a shift register, it to came to the same conclusion:

“So, after 5 iterations, the final value in the shift register, which is displayed in the “result” indicator, will be 32.”

The second from Michael Hansen:

The sequence represents a left shift operation (multiplication by 2) in each loop iteration. Let’s break it down:

Step-by-Step Execution:
Loop 1: 1 × 2 = 2
Loop 2: 2 × 2 = 4
Loop 3: 4 × 2 = 8
Loop 4: 8 × 2 = 16
Loop 5: 16 × 2 = 32
Conclusion:
This process is equivalent to a left shift.
