Question..16-26-(56)-36-46-(68)-56-
1)16+10=26
2)26+10=36
3)Leave 56..(56+12=68)
4)36+10=46
5)46+10=56
6)Leave 68 ..(68+12=80),
7)56+10=66
So the answer is 66,80.

Again as question 13, you consider two separate series ..
1st series..(starting wid 16)
16 ,26,36 ,46, 56, 66 ....They are increasing by 10

and the 2nd series (starting with 56) i.e
56 ,68, 80.. They are increasing by 12 !

that way you get 16 ,26 ,56 ,36, 46 ,68 ,56, 66,80....
