5,9,12,18,36,47,72.?

• question is wrng,data missng
  the qtn is 5, 9, 12, 18, 26, 36, 47, 72, _?
  then
  Ans:75
  Here In odd places, multiples of 7 are added i.e 5,5+7(=12),12+14(=26),26+21(=47),47+28(=75).
  Similarly for even numbers i.e multiples of 9 are added.

• 5, 9, 12, 18, 26, 36, 47, 72, _?
  it is 5 ...... 12....... 26......... 47
  12= 5+7
  26= 12+2×7
  47=26+3×7
  Next is 47+4×7=75
  and 9, 18, 36, 72 hence next 144
  Therefore 5, 9, 12, 18, 26, 36, 47, 72, 75, 144

• In case of even place how multiples of 9 are adding?
  9+9*1=18
  18+9*2=36
  36+9*3=63(but in series it 72 )

  firstly considering corresponding series term 5 ...... 12....... 26......... 47
  having logical arrangement as follows;
  12= 5+7
  26= 12+2×7
  47=26+3×7
  Next is 47+4×7=75
  and for the dropped series elements,they follows previous term*2 =final one so 9, 18, 36, 72 hence next 144
  Therefore 5, 9, 12, 18, 26, 36, 47, 72, 75, 144

• there is one term missing in the given series...i.e 26 aftr 18 .....
  ans will be 75..
  in odd places, multiple of 7 are added.
  12= 5+7
  26= 12+2×7
  47=26+3×7
  Next is 47+4×7=75

• series must be such like 5,9,12,18,26,36,47,72,75.....but in this series 26 missed, so question is wrong, but all solution r correct
