Write the first six terms of the sequence, beginning with n=1. a(n)=60n Enter the numbers, separated by commas.
Sever21 [200]

Answer:

60, 120, 180, 240, 300, 360

Step-by-step explanation:

a(n)=60n

At n =1

a(1) = 60(1) = 60

At n = 2

a(2) = 60(2) = 120

At n = 3

a(3) = 60(3) = 180

At n = 4

a(4) = 60(4) = 240

At n = 5

a(5) = 60(5) = 300

At n = 6

a(6) = 60(6) = 360

60, 120, 180, 240, 300, 360

Classify the sequence arithmetic , geometric, or neither
Feliz [49]

Answer:

Geometric

Step-by-step explanation:

Given terms are {3, -1, 1/3, -1/9............}

If we have common difference between the terms then it is arithmetic

If we have common ratio between the terms then it is Geometric

Difference of 3  and -1  is 4

Difference of 1/3  and -1 is -4/3

Common difference it not same so it is not Arithmetic

Now we check common ratio

we divide second term by first term

first term is 3  and second term is -1

\frac{-1}{3}

now we check with next two terms

\frac{\frac{1}{3}}{-1}=\frac{-1}{3}

common ratio is -1/3

So this is Geometric
