Which expression gives the number in the nth position in the sequence?
A) 2n - 2
B) 3n + 4
C) 4n - 1
D) 5n
Answer:
Option B is correct
3n+4[/tex]
Step-by-step explanation:
The nth term for the arithmetic sequence is given by:
....[1]
where,
is the nth position
n is the number of term
is the first term and
d is the common difference.
Given the table:
Position(n) Value of Term()
1 7
2 10
3 13
4 16
5 19
6 22
from the given table:
At n = 1 ,
At n = 2
at n = 3
and so on
Common difference(d) for the sequence is 3
Since,
⇒
Substitute d = 3 and in [1] we have;
⇒
⇒
Therefore, the expression gives the number in the nth position in the sequence is,
(x + 1)2 + (y - 2)2 = 3
(x + 1)2 + (y + 2)2 = 9
(x + 1)2 + (y - 2)2 = 9
Answer:
last option is correct.
Step-by-step explanation:
We have been given that
Center: (-1,2)
Radius : 3 units
We know that the standard form of the circle is given by
Here, h = -2, k = 2, and r=3
Substituting these values in the above formula, we get
Therefore, last option is correct.
6 + 5
-6 + 5
-6 + (-5)
