A boy is gifted a box of choclates. He plans his weekly consumption as 60,48,38,28,24,20,18. His mother agrees but says that he has to change one number so that a series is formed. What is the number that has to be changed?

• 28 should b changed
  the diff btw the numbers is decreasing by 2
  60-12=48
  48-10=38
  38-10=28
  28-4=24
  24-4=20
  20-2=18
  thus replacing 28 by 30 will make a pattern
  60-12=48
  48-10=38
  38-8=30
  30-6=24
  24-4=20
  20-2=18

• 28.. because then the seris will be 60,48,38,30,24,20,18
• 10 years agoHelpfull: Yes(16) No(1)
• 28 because diffrence
  20-18=2
  24-20=4
  30-24=6
  38-30=8
  48-38=10
  60-48=12.
  
  28 is disturbing the series.

• the number is 28 because series difference is 2,4,6,8,10,12.
  But 28 is not in series it comes with difference 4.

• the no. 28 should be changed it should be 30.the no. series is n+12,n+10,n+8,n+6,n+4,n+2
  The correct series is 60,48,38,30,24,20,18
