• 4)Let's start solving :
  Just remember
  Rule A: subtract 3
  Rule B : add half of the result
  Keep alternating between rule A and B in every alternate step.
  
  Step 1
  7 -3 =4 (rule A- by subtracting 3)
  
  Step 2
  4+ 2 = 6 ( rule B add half of the result of Step 1, ie half of 4 =2)
  
  Step 3
  6-3 = 3 (again Rule A- by subtracting 3)
  
  Step 4
  3+1.5 = 4.5 ( again rule B , add half of 3=1.5)
  
  Step 5
  4.5-3=1.5 (again, rule A, subtracting 3)
  
  Step 6
  1.5+0.75 = 2.25 ( again rule B , add half of 1.5=0.75)
  
  Step 7
  2.25-3 = -0.75 ( again rule A, by subtracting 3 )
