Answer:
Step-by-step explanation:
is given as the nth term of a sequence.
We want to find 
, which means we find the 7th term of the sequence.
Here, we simply substitute "7" into "n" of the formula given for to find the value of the 7th term of the sequence.
We show this below:
So the 7th term is "-15"
Right Triangle. Using the Pythagorean theorem: 3^2+4^2=5^2 9+16=25
A) $200.87
231------------------115%
X-----------------------100%
115x = 231x100
115x = 23100
Divide both sides by 115
X= 200.86956523
X= 200.87
Alright, so if the first number is x, the second number is y, and the third number is z, we have x+y+z=270. Next, since we know that x=y-1 since it is less than y by one and z=y+1, we have y-1+y+y+1=y+y+y=3y=270. Dividing both sides by 3, we get y=90
