An arithmetic sequence is represented by the recursive formula a1=17an=an−1−8 . What is the fourth term in the sequence? a4=−4 a
user100 [1]

Answer:

a₄ = - 15

Step-by-step explanation:

Using the recursive formula and a₁ = 17 , then

a₂ = a₁ - 8 = 17 - 8 = 9

a₃ = a₂ - 8 = 9 - 8 = 1

a₃ = a₂ - 8 = 1 - 8 = - 7

a₄ = a₃ - 8 = - 7 - 8 = - 15

4:3 19:11 equivalent ratios?
maria [59]

Answer:

No

Step-by-step explanation:

We can tell if these ratios are equivalent by dividing the numerators and denominators. <em>If we end up with the same result, these ratios are equivalent</em><em>.</em>

<em />

<em />\frac{4}{3}<em>   </em>\frac{19}{11}<em />

<em />

<em />19 \div 4 = 4.75\\\\11\div 3 = 3.\overline{66}<em />

<em />

These two numbers are not equivalent, so these ratios aren't equivalent to each other

Hope this helped!
