How is a number in the Pascal's triangle obtained?

• by getting the product of the two numbers directly above it.

• by getting the sum of the two numbers directly above it.

• by getting the difference of the two numbers directly above it.

• by getting the mean of the two numbers directly above it.

If the sign between the terms of the binomial is negative, its expansion will have signs which are

• all positive

• all negative

• alternate starting with positive

In the absence of the Pascal's triangle, the coefficient of any term of the binomial expansion can be obtained by dividing the product of coefficient of the preceding term and exponent of x of the preceding term by _____ of the preceding term

• the exponent of y

• the exponent of y + 1

• the exponent of y - 1

• the square root of y
