Question

Find out the missing number

0	-1	-2
1	0	-1
2	?	0

• A. 1
• B. -1
• C. -2
• D. 4

Answer 1

The correct option is A 1

The figure has a pattern comprising negative numbers and positive numbers. 0 is placed in 3 boxes diagonally in the figure. On each side are 3 boxes. On the side where there is no question mark there are two -1 and one -2

So there should be two positive 1 and one 2 on the other side as well. That's why the question mark should be replaced with a positive 1. Option A is the correct answer.
