60. 48, 38, 28, 24, 20, 18 what is the wrong number in the sequence?

• 18+2=20
  20+4=24
  24+6=30
  30+8=38
  38+10=48 so the wrong num is 28

• ans is 28
  60-48=12
  48-38=10
  38-30=8
  30-24=6
  24-20=4
  20-18=2
  so to make the correct order there should be 30 in series instead of 28

• No 28 is the wrong no.
  by adding 2,4,6,8,10 from LHS then the no will be 30 instead of 28..
  I think so...

• Ans:28
  the difference of two no form series
  48-38=10
  38-30=8(28 is replaced by 30)
  30-24=6
  24-20=4
  20-18=2

• 18+2=20
  20+4=24
  24+6=30 but here instead of 30 it is 28
  30+8=38
  38+10=48
  hence the wrong number is 28
