Answer 2

b. 10 is wrong in series 7, 7, 10, 24, 27, 135, 140, 980, 987.

• The pattern for this series is:
• 7*1=7
• 7+1=8(which is given as 10)

• 8*3=24
• 24+3=27

• 27*5=135
• 135+5=140

• The number is first multiplied and then to the answer of that we add the same number to give the next number and this pattern follows. Here instead of 10 8 should have been there.
