Which of the following equations could be used to solve for the tenth term of the following sequence? 15, 13, 11, 9, ...
omeli [17]

Answer

b) A(10) = 15 + 9(-2)


<u>Explanation</u>

15, 13, 11, 9, ...  This is an arithmetic sequence.

The common difference = 13 - 15 = -2

                                     or = 9 - 11 = -2

The first term of the sequence = 15.

The nth term of an arithmetic sequence is given by:

Tn = a + (n - 1)d

∴ T₁₀ = 15 + (10 - 1)(-2)

        = 15 + (9 × -2)  ⇒ This is the expression you need.

        = 15 + -18

       = -3

I need someone to teach me how to do at least half of these problems please help
Gwar [14]
Here, You need to substitute the value of x, and y, in the equation then check if L.H.S is equal to R.H.S or not. If they are equal then, ordered pair was correct, otherwise they are not applicable.

75) Here, oly option D can fit i the equation, we can check:
 3(-5) -2(-1) = -15+2 = -13 = R.H.S
So, the pairs are valid.

76) Here, only option D is your answer, 
4(2) - 4 = 8 - 4 = R.H.S

Do the same thing in every equation!

Hope this helps!
