Answer 2

Answer:

58

Explanation:

1 + 2  = 12 + 9 = 21

2  + 3  = 23 + 13 = 36

3 + 4 = 34 + 9 = 43

4 + 5 = 45 + 13 = 58

if you observe the pattern followed by the sequence we can see that the first numbers are added by 9 following by 13 and then 9 and then according to the pattern we need to add 13 for the last series.
