Q. What is the next number of the following sequences
115,100,86,74,65,60,?

• 115,100,86,74,65,60,?
  115-15=100
  100-14=86
  86-12=74
  74-9=65
  65-5=60
  60+0=60(ans)(-15+1=-14,-14+2=-12,-12+3=-9,-9+4=-5,-5+5=0)

• 115-15=100
  100-14=86(15-1=14)
  86-12=74 (14-2=12)
  74-9=65 (12-3=9)
  65-5=60 (9-4=5)
  60-0=60 (5-5=0)

• 115-100=15
  100-86=14
  86-74=12
  74-65=9
  65-60=5
  15-14=1,14-12=2,12-9=3,9-5=4, so the no should be such dats gives a diff of 5 now that could be 60 itself as 60-60=0 so 5-0=5 or 70 so that 10-5 =5.

• 115 100 86 74 65 60 x (diffirence b/w the no)
  
  15 14 12 9 5 60-x=y
  
  1 2 3 4 (so this/next no is 5,...that means Y should be ZERO...Y is zero if and only if X is 60)
  
  so ans is X=60
  
  final series is "115,100,86,74,65,60,60"

• (115 -100) (100-86) (86-74) (86-65) (65-60)
  15 14 12 9 5
  
  (15-14) (14-12) (12-9) (9-5)
  1 2 3 4 so that the next will be 5 >> (5-5) >> 0 so, 60+0=60
