The number is 5.

Step-by-step explanation:

Finding the Number

To find the number, we have to form the algebraic equation first by translating the given mathematical problem above to algebraic expression. The algebraic equation is a statement that shows the equality of two algebraic expressions.

Equation:

Let "x" be the number.

"four times the square of a number" = 4x²

"20 times that number" = 20x

"four times the square of a number equals 20 times that number"

4x² = 20x

Solution:

4x² = 20x

4x²/4x = 20x/4x

x = 5

Final

The number is 5.

Checking:

To check, substitute the number.

4x² = 20x

4(5²) = 20(5)

4(25) = 100

100 = 100 ✔

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
