alleryAdding the two ones in the row for index one gives which entry below?
AThe number six
BThe number one
CThe number two

Answer & Solution
Correct answer: C. The number two
1. Each entry is the sum of the two above it.
2. One plus one gives the entry in the next row.
3. The addition of ones in the row for index 1 gives rise to 2 in the row for index 2.
4. So the answer is two.
