4. 10+3 = 13
   13+5 = 18
   18+7 = 25
   25+9 = 34

Therefore, the correct answer is 26. This series are followed the increasing pattern by 2 from every previous elements i.e. (3,5,7,9).


5. 2+1 = 3
   3+2 = 5
   5+3 = 8
   8+4 = 12
   12+5 = 17

So that the correct answer is 17.This series are followed the increasing pattern by 1 form every previous elements i.e. (1, 2, 3, 4, 5).


6. 7+4  = 11
   11+2 = 13
   13+4 = 17
   17+2 = 19
   19+4 = 23

Therefore, the correct answer is 23. This series followed the first adding 4 and second declining by 2 every interval.


7. 2+6 = 8
   8+6 = 14
   14+6 = 20
   20+6 = 26

Therefore, the correct answer is 26.This number series followed adding by 6 for every number of series.


8. 3*3+1 = 10
   4*4+1 = 17
   5*5+1 = 26
   6*6+1 = 37
   7*7+1 = 50

Therefore, the correct answer is 50. This series follow the squaring every regular number and adding by 1 for all number of series.


9. 3+5 = 8
   8+7 = 15
   15+9 = 24
   24+11 = 35
   35+13 = 48

Therefore, the correct answer is 48. This series are followed the increasing pattern by 2 from every previous elements i.e. (5, 7, 9, 11, 13,...). 


10. 20+10 = 30
    30+12 = 42
    42+14 = 56
    56+16 = 72

Therefore, the correct answer is 72. This series are followed the increasing pattern by 2 form every previous elements i.e. (10, 12, 14, 16,....).
