Answer:
a geometric sequence is a sequence of numbers that follows a pattern where the next term is found by multiplying a constant called the common ratio which is R
Step-by-step explanation:
in a geometric series you multiply the n th term by a certain common ratio are in order to get (n+1)th term in arithmetic series you can add the common difference D to the n th term in order to get (n+1) th term.
<span>I am detailing it to show you how to calculate an explicite equation
Arithmetic Progression First term 7 , second 3 hence d=3-7 = - 4</span>
n=Term rank ==>║ 1 2 3 4 5 6 7......n
Value ====>║ 7 3 -1 -5 -9 -13 -17.......
a(n) (sub Notation║ a₁ a₂ a₃ a₄ a₅ a₆ a₇.....a(n)
Term 1 = a₁ = 7........................7-4(0)
Term 2 = a₂ = 3........................7-4(1)
Term 3 = a₃ = -1.......................7-4(2)
Term 4 = a₄ = -5.......................7-4(3)
Term 5 = a₅ = -9.......................7-4(4)
Term n = a(n) ============7-4(n-1)
So A. an = 7 − 4(n − 1); all integers where n ≥ 1
Answer: 1), 2) and 5) are equivalent.
Step-by-step explanation:
Since in first expression, 2+x=5 ⇒ x= 5-2= 3⇒x=3
In second expression, x+1=4⇒ x=4-1⇒x=3
In third expression, 9+x=6 ⇒ x=6-9⇒x= -3
in Fourth expression, x+(-4)=7 ⇒ x=7+4 ⇒ x=11
In fifth expression, -5+x=-2⇒ x=-2+5 ⇒x=3
Thus, 1) 2) and 5) expression are giving the same result.
Therefore they are equivalent to each other.

Answer:
1-A.) 0.14
; 2-C.) 0.3
Step-by-step explanation:
There are 41 people less than 20 years old who have an iron deficiency. There are 300 total people. This gives us the probability
41/300 = 0.136666 ≈ 0.14
There are 43+46 = 89 people greater than 20 years old who do not have an iron deficiency. There are 300 total people. This gives us the probability
89/300 = 0.29666 ≈ 0.30 = 0.3
