Q. Find the 8th term of this series 0,6,6,20,20,42......

• 0*1=0
  2*3=6
  2*3=6
  4*5=20
  4*5=20
  6*7=42
  6*7=42
  8*9=72
  8*9=72
  so 72 is the answer

• 72
  everytime increasing,+6,0,+14,0,+22,0,30
  +8 +8 +8
  so the next term will be=42+30=72

• 1*1-1 = 0
  2*2+2 = 6
  3*3-3 = 6
  4*4+4 = 20
  5*5-5 = 20
  6*6+6 = 42
  7*7-7 = 42.....
  so 8th term will be 42

• The technique is n^2*n
  As:
  1.for 0: 0^2+0=0
  2.for 2: 2^2+2=6
  3.for 4:4^2+4=20
  4.for 6:6^2+6=42
  5.for 8:8^2+8=72
  i.e, for even value series and repeat the number once thats it :)

• 72 is the answere
  2*3=6
  =3+7=10
  2*10=20
  =10+11=21
  2*21=42
  =21+15=36
