4, 3, 8, 4, 24, 13, 60, ?

• Ans is 38
  alternate of 4 no.
  8= 4+(2^2)
  24=8+(4^2)
  60=24+(6^2)
  :
  :
  alternate of 3
  4=3+(1^2)
  13=4+(3^2)
  38=13+(5^2)

• 4,8,24,60 and 3,4,13 are two series
  find diff first
  4,16,36 (which are squares of 2,4,6)
  1,9 ( squares of 1,3) so nxt in this series will be square of 5
  i.e 25 ..... 13+25=38

• just look the alternate number bcoz we have to find alternate number only so
  we will concider this number 3 4 13 ?
  3+1^2=4
  4+3^2=13
  13+5^2=38

• easy way..It contain 2 series....
  multiply the odd place numbers with "prime nos" 2,3,5,7.....
  4*2=8
  8*3=24
  24*5=60
  
  even place nos
  3+ 1^2=4
  4+ 3^2=13
  13+5^2=38
  so ans=38....

• 25 is ans...bcz4 and 8 diffrens is 4 8 and 24 diffrens 16 these are even no square...3 ana 4, 4and 13 diffrens is coming for odd no square so ans is25

• Thanks........@Warun.
  V good Solution.
  
  Ans: 38
  Alternate of 4 nos.
  8= 4+(2^2)
  24=8+(4^2)
  60=24+(6^2)
  :
  And
  :
  Alternate of 3
  4=3+(1^2)
  13=4+(3^2)
  38=13+(5^2)

• 3= 4/2 +1,
  4 = 8/2
  13=24/2 +1
  so 30 = 60/2

• 3+1=4
  4+3^2=13
  13+5^2=38

• correct solution's are
  there are two series 4,8,24 & 60 are the 1st series
  and 3,4,13 are the second series.
  first series obeys this rules....
  4= 4+(1)^2
  8= 4+(2)^2
  24=8+(4)^2
  60=24+(6)^2
  
  second series (3,4,13) obeys this rules
  4=3+(1)^2
  13=4+(13)^2
  so 13+(5)^2=38...is the correct answer...thank you..

• 4-3=1
  8-4=4 & 4-1=3
  24-13=11 & 11-4=7
  
  => 11+11=22
  & 60-38=22
  
  Ans. 38
