Ahat [919]

Answer:  \bold{a)\quad 51, 54, 57\qquad a_n=a_{n-1}+3}

               \bold{b)\quad 250, 625, 1562.5\qquad a_n=(2.5)a_{n-1}}

<u>Step-by-step explanation:</u>

a) This is an arithmetic sequence where 3 is added to the previous term.

48 + 3 = 51

              51 + 3 = 54

                            54 + 3 = 57

The recursive formula for this sequence is:  a_n = a_{n-1}+3

*****************************************************************************************

b) This is a geometric sequence where 2.5 is multiplied to the previous term.

100(2.5) = 250

                250 (2.5) = 625

                                    625(2.5) = 1562.5

The recursive formula for this sequence is: a_n=(2.5)a_{n-1}

I need an explanation for the problem 4v2=-12v-9. I don't understand why it factors into 4v+3 and 4v+3
kirza4 [7]

Answer:

The factors are 2v+3,2v+3.

The factors are not 4v+3,4v+3

Step-by-step explanation:

Equation is 4v^2=-12v-9.

This equation can be written as follows:

4v^2+12v+9=0

Here,

12v=6v+6v

Therefore,

4v^2+6v+6v+9=0\\2v(2v+3)+3(2v+3)=0\\(2v+3)(2v+3)=0

So, the factors are 2v+3,2v+3.

The factors are not 4v+3,4v+3
