-3r + 18 = 15r please help!!
Luba_88 [7]

Answer:

r = 1

Step-by-step explanation:

Step 1: Write equation

-3r + 18 = 15r

Step 2: Solve for <em>r</em>

  1. Add 3r to both sides: 18 = 18r
  2. Divide both sides by 18: 1 = r
  3. Rewrite: r = 1

Step 3: Check

<em>Plug in r to verify it's a solution.</em>

-3(1) + 18 = 15(1)

-3 + 18 = 15

15 = 15

Consider the sequence 130, 143, 156, 169, ...    Write an explicit formula to represent the arithmetic sequence and use it to fi
Hunter-Best [27]

Answer:

A(n)=130+13(n-1) ; 86

Step-by-step explanation:

Here is the sequence

130,143,156,169.......

the first term denoted by a is 130 and the common difference denoted by d is second term minus first term

143 - 130 = 13

Hence a=130 and d = 13

Now we have to evaluate to 13th term.

The formula for nth term of any Arithmetic Sequence is

A(n) = a+(n-1)d

Hence substituting the values of a ,and d  get

A(n)=130+13(n-1)

To find the 13th term , put n = 13

A(13)=130+13*(13-1)

      = 130+13*12

      = 130+156

A(13) = 286
