Complete the series:
4,-5,11,-14,22,__

• see the difference b/w numbers. Its -9,16,-25,36,-49. So 22-49=-27 is ans

• 2nd number in series=1st number-(3*3)=-5
  3rd number=2nd number+(4*4)=11
  4th number=3rd number-(5*5)=-14
  5th numer=4th number+(6*6)=22
  6th number=5th number-(7*7)=-27

• Here,4 and (-5)difference is -1...eq(i);(-5)and 11 diff is 6...(ii);11 nd (-14) diff is -3...(iii);(-14) nd 22 diff is 8...(iv).Then,(-1-2=-3)(where -1 from eq(i)-2).then,(6+2=8)then,(-3-2=-5).so between 22 nd (-27) diff are -5.that's why ans is -27.

• 4,-5 > digit diff=9
  -5,11 > digit diff= 9+7=16
  11,-14 > digit diff=16+9=25
  -14,22 > digit diff= 25+11=36
  22, -x > digit diff= 36+13=49
  hence x= 49-22=27 bt with a -ve sign
  so ans is -27

• check the difference of alternate numbers it is increasing by two...
  11-4=7
  -14--5=-9
  22-11=11
  x-(-14)=-13
  =>x=-27
  the signs also change alternately

• -27
  4+7=11
  -5+(-9)=-14
  11+11=22
  -14-13=-27 for positive add next positive number for negative add negative odd number
