Look at the pattern in the results:
6 + 9 = 61
5 + 8 = 46
4 + 7 = 33
3 + 6 = 22
Now observe the answers:
61 → 46 → 33 → 22
Find the differences:
61 − 46 = 15
46 − 33 = 13
33 − 22 = 11
The differences are decreasing by 2 each time:
15, 13, 11
So the next difference should be:
11 − 2 = 9
Now subtract 9 from 22:
22 − 9 = 13
So,
1 + 1 = 13 ✅
