A. 26

B. 28

C. 40

D. 48

• 4*3-2=10
  82*3-2=244
  244*3-2=730
  hence 10*3-2=28

• ans is -58
  in this 2 series we have
  -23,-16,-52,-45,-65
  18,14,37,33
  the diff bwn 1st two numbers in -ve series is 7
  n in +ve series is 4
  -23+7=-16
  -52+7=-45
  -65+7=-58
  18-4=14
  37-4=33

• 3^1+1=4
  3^2+1=10
  3^3+1=28

• 10*3 - 2 = 28
  28*3 - 2 = 82
  82*3 - 2 = 244
  244*3 - 2 = 730.
  or,
  3^2+1 = 10
  3^3+1 = 28
  3^4+ 1 = 82
  3^5 +1 = 244
  3^6 +1 = 730.

• Ans : 28
  730-244=486
  244-82=162(486/3)
  82-28=54(164/3)
  28-10=18(54/3)

• 1. 10
  
  2. (10*3) -2 = 28
  
  3. (28*3)-2 = 82
  
  4. (82*3) -2 = 244
  
  5. (244*3) -2 = 730
