  4,5,9,18,34,59
  
  5-4=1
  9-5=4
  18-9=9
  34-18=16
  so, 34+25=59

• ans: 59
  5-4 =1 = 1^2
  9-5 =4 = 2^2
  18-9 = 9 = 3^2
  34-18 = 16 =4^2
  5^2 =25+34= 59

• 4,5 difference 1=>1^2=1
  5,9 difference 4=>2^2=4
  9,18 difference 9=>3^2=9
  34,18 difference 16=>4^2=16
  so the next number and 34 difference will be 25 so 34+25=59
  59 is the answer

• Q2. 11,8,17,14,23,24,31,32,?
  Select 11,17,23,31,?
  Very next prime number to 11 is 13 but it is missed but and further Prime 17 is present
  Very next prime number to 17 is 19 but it is missed but and further Prime 23 is present
  Very next prime number to 23 is 29 but it is missed but and further Prime 31 is present
  Very next prime number to 31 is 37 but it will be missed but and further Prime is 41 is present.
  So I think Ans is 41

• 4,5,9,18,34
  i.e
  diff between each two number is 1,4,9,16 so last will 25 so answer will be 59

• 5-4 =1
  9-5=4
  18-9=9
  34-18=16
  we have a difference of natural numbers.so the next term will be 59.
  34+25 =59.

• 5-4=1 i.e. 1 sq
  9-5=4 i.e 2 sq
  18-9= 9 i.e 3 sq
  34-18=16 i.e 4 sq
  next will be sq of 5 i.e 25
  so 25+34=59

• 59 . the difference between the numbers is in square terms 5-4=1 (1^2) , 9-5=4 (2^2), 18-9=9 (3^2) and so on

• 5-4=1=1^2
  9-5=4=2^2
  18-9=9=3^2
  34-18=16=4^2
  so we add 5^2=25
