= 20142015 20152014 Therefore, –3 must be subtracted.
– (20142015 – 1)(20152014 + 1) Reasoning
= 20142015 20152014 – 6. (A) The given series is repeating after every five
(20142015 20152014 shapes and the shading moves by one shape
+ 20142015 –20152014 – 1) towards left. Hence, the missing shape is
.
= 20142015 20152014 – 20142015
20152014 – 20142015 + 20152014 + 1) 7. (D) Count the number of lines in each figure.
