The answer for 153 X 15 is 2,295!
What is the question here?
Answer:
88
Step-by-step explanation:
We are given that in arithmetic sequence , the nth term
is given by the formula

Where 
d=Common difference
In an geometric sequence, the nth term is given by

Where r= Common ratio
1,4,7,10,..
We have to find 30th term.







Therefore, given sequence is an arithmetic sequence because the difference between consecutive terms is constant.
Substitute n=30 , d=3 a=1 in the given formula of arithmetic sequence
Then, we get

Hence, the 30th term of sequence is 88.
Answer:
y = 2x-2
Step-by-step explanation:
First find the slope of the line
x+2y=6
2y = -x+6
y = -1/2x +3
This is in slope intercept form ( y = mx+b) so -1/2 is the slope
We want a line that is perpendicular so take the negative reciprocal of the slope
- ( 1/ (-1/2)) = 2
The slope of the perpendicular line is 2
y = 2x+b
Substitute the point into the equation
8 = 2(5) +b
8 = 10+b
-2 =b
The equation of the line perpendicular is
y = 2x-2
