Can you find the missing number? This number has a single digit.

8 → 7

7 → 3

3 → 5

5 → ?

Good luck!

I think that 5 maps to

5

because it takes

5 segments to display the number 5 in a seven segment display.

This fits the pattern for the other numbers:
- 8 takes 7 segments
- 7 takes 3 segments
- 3 takes 5 segments

I think the answer is

5 $\rightarrow$ 5

Reasoning

For each digit count the number of lit segments in a seven-segment display of the number.
8 has 7 lit segments, 7 has 3, 3 has 5 and 5 has 5.
