What is the 8th term of the arithmetic sequence with a first term of 7 and a common difference of -3?
Answers
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.
What is Arithmetic progression?
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

10 x 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
100 x 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000. which is the lowest and common? 100
7/10 /100 how many times can 10 go into 100? 10 times. so we will multiply 10 time the numerator which is 7, and now will be 70/100
6/100 /100 how many times can 100 go into 100? 1 time. so we will multiply 1 time the numerator 6 which equals 6. 6/100
now add the new fractions. 70/100 + 6/100 = 76/100

they want to pay 20% additionally, so that would be written as . . .
$47.60(100% + 20%)
$47.60(120%)
$47.60(1.20)
The expression that can be used to determine the total bill is 1.20 x ($47.60)
What is the expression?
The total bill paid is the sum of the cost of the meal and the value of the tip.
Cost of the meal = $47.60
Cost of the tip = 0.20 x $47.60
Total cost of the meal = 1.20 x ($47.60)

Answer: x<3 and x>2
For 4x-4<8, add 4 to 8 making it 12. Divide 12 by 4 from the 4x, making it x<3.
For 9x+5>23, subtract 5 from 23 making it 18. Divide 9 from 9x and 18 leaving you with x>2
