If you reduce these fractions into simplest form 5/20 is 1/4 because the numerator and denominator can be divided by 5. 9/12 reduced is 3/4 because the numerator an denominator can be divided by 3.

Find the second, fourth, and eleventh terms of the sequence A(n) = 5 + (n - 1)(-3)

klio [65]

Answer:

2nd: 2

4th: -4

11th: -25

Step-by-step explanation:

When you substitute a number into the equation you get that number term. So, if you substituted in 1, you get the first term. To find the second term, you substitute in 2:

A(2) = 5 + (2 - 1)(-3)

A(2) = 5 + (1)(-3)

A(2) = 5 - 3

A(2) = 2

To get the 4th term you substitute in 4:

A(4) = 5 + (4 - 1)(-3)

A(4) = 5 + (3)(-3)

A(4) = 5 - 9

A(4) = -4

And we do the same for the 11th term:

A(11) = 5 + (11 - 1)(-3)

A(11) = 5 + (10)(-3)
