TCS Company Numerical Ability Sequence and Series

Arjun mother kept a box of chocolates in the refrigerator .Arjun put up a daily plan of how many chocolates he would consume in the week. He represented that as diminishing stock as 60, 48,38,28,24,20,18.Mother said that his plan would be approved , Provided he corrected one of the figures to make it a proper series .Which one did Arjun Correct?

Read Solution (Total 3)

60,48,38,28,24,20,18

18,20,24,30,38,48,60
+2,+4,+6,+8,+10,+12

28 should be replaced by 30

in place of 28, it would have been 30.
so now the difference is 10,8,6,4,2

the series is given as 18,20,24,28,38....
the logic is that even numbers are added
18+2=20
20+4=24
24+6=30
30+8=38
so here 28 is wrong
it should b replaced by 30
so 28 is wrong
