In 1960, the world record for the men’s mile was 3.91 minutes. In 1980, the record mile was 3.81 minutes. Write a linear model that represents the world
record (in minutes) for the men’s mile as a function
of the number of years since 9160.
Use the model to estimate the record time in 2020
and 2040. How accurate is the 2020 estimate?

i can answer this question sweetie!

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
