• (3)(1,3,1,2.5), (5,1,4,5), (4,8,7,_)
  ans: 9.5
  (1+3+1)/2=2.5
  (5+1+4)/2=5
  (4+8+7)/2=9.5

• Q4. grouping on the alternative basis
  1st,3rd,5th,7th term : 1/2, 1/2*1/2=1/4 , 1/4*1/2=1/8 ,1/8*1/2=1/16
  2nd,4th,6th,8th term : 1/2*1/3=1/6 , 1/6*1/3=1/18
  so 1/18*1/3 =1/54

• Q4,1/2,1/2,1/4,1/6,1/8,1/18,1/16,1/54
  
  In this srs odd term multiply with 1/2 and even term multiply with 1/3
  (I) 1/2*1/2=1/4(III)
  (III)1/4*1/2=1/8(V) and so on
  (II) 1/2*1/3=1/6(IV)
  solve all after that 1/54 is coming

• First question may be like this
  1/4, 1/4, 1/2, 1.5, 6, ?
  So
  1/4*1=1/4
  1/4*2=1/2
  1/2**3=1.5
  1.5*4=6
  6*5=30 ( Ans )
