Find the fourth term of an arithmetic sequence if the first term is 12 and the common difference is -3. A (subscript 4)=???
storchak [24]

Answer:

The fourth term of the sequence is 3

Step-by-step explanation:

For an nth term in an arithmetic sequence

A(n) = a + (n - 1)d

Where n is the number of terms

a is the first term

d is the common difference

From the question

a = 12

d = - 3

So the fourth term of the sequence is

A(4) = 12 + (4 - 1)-3

= 12 + (3)(-3)

= 12 - 9

The final answer is

3

Given : A mountain path is 12.1 miles long.

a hiker walks along the path at a rate of 1.96 miles per hour

To Find: in approximate how many hours will the hiker walk the entre trail

Distance = 12. 1 miles

Speed = 1.96 mile/hr

Distance = Speed * time

12.1 = 1.96 * t

=> t = 12.1/1.96

=> t = 6.17

=> t ≈ 6 hrs 10 mins
