Consider a sequence given by the formula f(n)=3n-1 starting with n=1. Generate the first 5 terms of the sequence

Rufina [12.5K]

Answer:

The first 5 terms are 2, 5, 8, 11, 14.

Step-by-step explanation:

You use the formula to find out each term.
f(n)=3n-1 starting with n=1. If n=1 that is the 1st term, if n=2 that is the 2nd term, and so on. n means what number term it is.
Now to find each term:

n=1: f(1)= 3(1)-1= 3-1= 2 The 1st term is 2
n=2: f(2)= 3(2)-1= 6-1= 5 The 2nd term is 5
n=3: f(3)= 3(3)-1= 9-1=8 The 3rd term is 8
n=4: f(4)= 4(3)-1= 12-1= 11 The 4th term is 11
n=5: f(5)= 5(3)-1= 15-1= 14 The 5th term is 14

So the first 5 terms are 2,5,8,11,14

Sea World has 9 aquariums with small fish in them and the number of fish in each tank are shown below: 45, 10, 48, 19, 36, 25, 6

crimeas [40]

Answer:

Step-by-step explanation:

To find the range, subtract the lowest number from the highest number

Arrange the numbers from least to greatest

45, 10, 48, 19, 36, 25, 63, 14, 37

10, 14, 19, 25, 36, 37, 45, 48, 63

The highest number is 63, and the lowest is 10

Now, subtract the lowest (10) from the highest (63)

highest - lowest

63-10

So, the range of the number of fish is 53

Describe a way to check the correctness of a subtraction answer.

Tamiku [17]

Step-by-step explanation:

Well in general, we can represent subtraction as: $x-y=z$

"z" represents the difference, and it really just represents x with y taken away. So if we were to "give back" this y value, we should get "x".

This means that: $z+y=x$

So one way to check, is adding the value that's being subtracted (y value) and the difference (z value), this should get you the value that is being subtracted from (x value). If you don't get the original value that's being subtracted from (x-value) then you know the answer you got is wrong.
