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
