2^2,2^3,2^-1,8^4,8^7,8^-3,11^5,11^3,11^2,14^6,14^9

• 2^2 then 2^3 where powers of 2 i.e. 2-3=-1
  therefore next term 2^-1
  similarly 8^4 & 8^7 where 4-7=-3
  therefore next term 8^-3
  so the answer is 14^-3 (Continuing this process)

• 14^-3
  here 2^2 then 2^3 so next is 2^-1 so it get by 2-3=-1 ,so in 8^4,8^7 then nest is 8^-3 it is get by 4-7=-3 it become 8^-3 so in last 14^6,14^9 then 6-9=-3 so 14^-3

• Ans : 2^2, 2^3, 2^-1 =2^2+1 then we will get middle number as 2^3
  8^4, 8^7, 8^-3 = 8^4+3 then we will get middle number as 8^7
  11^5,11^3, 11^2 = 11^5-2 then we will get middle number as 11^3
  similarly 14^6,14^9,14^15 =14^9 then we will get middle number as 14^9
  so tha ans is 14^15 or 14^-15 according to choice

• 14^-3
  this is because the series is in the order: the power of the third number= power of the first number -power the next number. Here number refers to the base number( all the three bases must be same)
