a. 38
b. 50
c. 64

• 50 is the ans.
  coz 8-2=6
  18-8=10
  32-18=14
  nd so on 32+18=50

• 6 10 14 18
  32+18=50

• the answer is 50 because 2=2*1
  8=4*2
  18=6*3
  32=8*4
  therefore 10*5=50

• b.50
  the difference b.w in each is first 10,then 14 then 18

• difference between first two number is 6,then the difference is increased by 4 respectively.so the answer is 50
  
• 9 years agoHelpfull: Yes(0) No(0)
• there is gap of 4 between each number for eg : 2+4=6 now add this 6 to the first number 2 to get the next number in the sequence tht is 8 . similarly for next number 18 we need to add 4 to the previous difference which ws 6 that is 6+4= 10 which means the next number in the sequence tht is 18 is reached by adding 10 to previous number 8 to get 18. now short cut:
  prev diff+4 = a now add this to prev number
  2+4=6 now 6+2=8
  6+4=10 now 10+8=18
  10+4=14 now 18+14=32
  14+4=18 now 32+18=50
  answer is b

• In this series, it's square of serial no.s with a multiplication of 2
  Ex: ((1)^2 ) * 2= 2
  ((2)^2 ) *2= 8
  ((3)^2 ) *2=18
  ((4)^2 ) *2=32
  ((5)^2 ) *2=50
