• multiply by 2 and then add 2
  multiply by 3 and then add 3
  So finally 160*5=800,800+5=805

• (5*2)+2 = 12, (12*3)+3 = 39, (39*4)+4 = 160 and (160*5)+5 = 805
  
  (10*3)+6 = 36, (36*4)+12 = 156 and (156*5)+18 = 798.

• Ans : 804,805
  i think its combination of two series.
  1. 5,12,36,160,?
  2. 10,36,156,?
  
  in the second series :
  10*3+(2^1)*3 = 36
  36*4+(2^2)*3 = 156
  156*5+(2^3)*3 = 804
  
  in the second series :
  5*2+2=12
  12*3+3=39
  39*4+4=160
  160*5+5=805
  
  So the numbers are 804 and 805.

• the next number will be 800 ,805
  5
  10=5+5
  12=10+2 in 10 we add two times 5 so here 10 +2
  36=12+12+12
  39= 12+12+12 +3 beacuse here we add 3 times 12 so 39
  156=39+39+39+39
  160= 156+4 beacuse 39 is 4 times
  800=160+160+160+160+160
  805 = 800 + 5 bcs 160 is 5 times

• take pairs of two numbers and you see that tow series are in the question so,
  5*2=10, 12*3=36, 39*4=156,160*5=800, and the add the number into the result of last digit i.e. 8 because the difference is 5
• 6 years agoHelpfull: Yes(0) No(0)
• 800,805 ,first multiply 5 by 2 =10,then add 2=12
  then multiply 12 by 3=36,then add 3=39
  then multiply 39 by 4=156,then add 4=160
  then multiply 160 by 5=800,then add 5=805
• 6 years agoHelpfull: Yes(0) No(0)
• so suppose the series is a,b,c,d,e,f,g,h ..
  a=5
  b=5*2 (as b is second term)
  c=5*2 +2
  d=12 * 3
  3=12 * 3 +3
  and so on
  so the missing terms are
  160*5= 800
  and 160*5 +5=805
  so the terms are 800,805
