Answer:5
Step-by-step explanation:
The solution is, the 8th term of the arithmetic sequence with a first term of 7 and a common difference of -3 is, a_8 = - 14.
An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with a common difference of 2.
The nth term of AP : a_n = a + (n – 1) × d
here, we have,
we know that,
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = - 3,
thus,
a_8 = 7 + (7 × - 3) = 7 - 21 = - 14
Hence, The solution is, the 8th term of the arithmetic sequence with a first term of 7 and a common difference of -3 is, a_8 = - 14.

Answer:
= - 14
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = - 3, thus
= 7 + (7 × - 3) = 7 - 21 = - 14

Answer: 21 states
Step-by-step explanation:
Since, The total number of states in the continental United States is 48 in which some are in the border of ocean and some are not in the border of ocean.
According to the question,
The ratio of the states having the border to the ocean and not having the border to the the ocean = 7 : 9
Let the states having the border to the ocean = 7x
The the states do not having the border to the ocean = 9x
Thus, 7x + 9x = 48
⇒ 16 x = 48
⇒ x = 3
Thus, the states having the border to the ocean = 7 × 3 = 21
In the continental United States, the number of states that border an ocean is 7/16 of the total number of states.
To find the number of states that border an ocean, we need to determine the specific values that correspond to the ratio. Let's denote the number of states that border an ocean as 7x and the number of states that do not border an ocean as 9x, where x is a common factor.
According to the given ratio, the equation is:
7x : 9x
To simplify the ratio, we can divide both sides by x:
7 : 9
Now, we can analyze the ratio. Since it is stated that the ratio applies to the continental United States, the total number of states is irrelevant. We are only concerned with the proportion of states that border an ocean to those that do not.
Based on the simplified ratio of 7:9, we can conclude that out of every 16 states, 7 of them border an ocean while the remaining 9 do not.
Therefore, in the continental United States, the number of states that border an ocean is (7/16) of the total number of states.
