Answer:

34

Step-by-step explanation:

1+4=5 2+5=12 3+6=21 5+8= ??

It is noticed that the previous solution is added to the unknowns and the cycle continues.

The previous solution is 5 which is added to 2 and 5 to give 12

5+2+5=12

12 is then added to the next set of unknowns 3+6 to give 21

12+3+6=21

21 is then added to the 5+8 to give 34

21+5+8= 34
