It is Arithmetic. It follows a pattern of divide by 2, which gives it the name "Arithmetic" and you can think of it as "Arithmic," which sounds like rythm. It follows the rythm of Divide by 2. Hope this helps, and let me know if I made any mistakes!
Arithmetic is a sequence that you constantly add or subtract by only 1 number. For example: 30, 25, 20, 15, etc. You are constantly subtracting 5; or 15, 20, 25, 30, etc. You are constantly adding 5. So these sequences would arithmetic. Geometric is when you divide or multiply by only 1 number. For example: 5,,25, 125, 625, etc. You are constantly multiplying the numbers by 5; or 625, 125, 25, 5, etc. You are constantly dividing by the number 5. So, these would be geometric. 1.6, 0.8, 0.4, 0.2 would be a geometric sequence. Geometric is the correct answer, because you are constantly dividing by 2.
Michelle read twice as many book as Zeke. This will be: = 2 × z = 2z
Tay read 3 more books than Zeke. This will be: = z + 3
The expression that represents the total number of books read over the summer by Zeke, Michelle and Tay would be the addition of the books read by each person. This will be:
You already know that the y-intercept in -32 for every equation by plugging in 0 for x, so disregard the coordinate (0,-32). Plug in -2 and 4 as your x values and check if they are equal to your y-value 0.
