Given: 22,26,34,41,46,56,67,?
Diff: 4, 8, 7, 5,10,13,?

Logic:
22-->2+2=4 ---> 22+4=26.
Next
26-->2+6=8 ---> 26+8=34.
...
67=6+7=13 ---> 67+13=80.

So, the ans is 80.

Given: 22,26,34,41,46,56,67,?
Diff: 4, 8, 7, 5,10,13,?

Logic:
22-->2+2=4
Now, 22+4=26.

26-->2+6=8
Now, 26+8=34.

Likewise
67=6+7=13,
Now, 67+13=80.

So, the seq becomes: 22,26,34,41,46,56,67,80.

the next number in the series is the sum of the digit in the number and itself
22+4=26
26+8=34
34+7=41
41+5=46
46+10=56
56+11=67
So 67+13=80
