1370,1320,1070,-180.?

• 1370,1320,1070,-180, -6430
  1370-5*10=1320
  1320-5*5*10= 1070
  1070-5*5*5*10= -180
  -180- 5*5*5*5*10= -6430
  nth term for n>1
  Tn = 1370-10*5^(n-1)

• Answer is: -6430
  solution:
  1370 - 1320 = 50
  1320 - 1070 = 250 (5*50)
  1070 - (-180) = 1250 (5*250)
  -180 - (x) = 6250 (5*1250)
  -x = 180 + 6250 = 6330
  x = -6430

• ans is -6430
  diff. of continuous digit is 50, 250, 1250..they are in GP
  so next diff must be 6250...
  hence next digit is -180-6250 = -6430

• -6430
  
  1370-50 = 1320
  1320-5*50=1070
  1070-5*5*50 = -180
  -180-5*5*5*50 = -6430

• ans is -6430
  bcz there is diff....50,250,1250 and next will be 6250
  so -180-6250=-6430
