10, 1, 11, 2, 13, 4, 17, 8, 25, 7, 32, 5, 37, 10, 47, 11, 58, 13
How did you get the 7 after the 25? It’s not supposed to be 7…
10,1,11,2,13,4,17,8,25,16,41,32
10, 1, 11, 2, 13, 4, 17, 8, 25, _, _, _
add the two digits from 10, or one and zero to get the 2nd number
1 + 0 = 1,
add the first and second number to get the third
10 + 1 = 11
again, add the two digits from the third number to get the fourth
1 + 1 = 2
keep repeating the pattern
11 + 2 = 13
13 + 4 = 17
1 + 7 = 8
17 + 8 = 25
2 + 5 = 7
25 + 7 = 32
3 + 2 = 5
I haven’t cheated by looking at google for the answer, this is just the first pattern I noticed in the sequence.
ok, NOW I searched on google and found the explanation.

So, I had the even term as the sum of the digits of the previous term, and the odd term as the sum of the previous two terms.
I still don’t think my answer was wrong, just different. 🙂
Ah, I see it now. There are two correct answers…
