An arithmetic sequence is one where each term is a constant difference, called the common difference, from the preceding term. The arithmetic sequence can always be expressed as:
a(n)=a+d(n-1), a=first term, d=common difference, n=term number.
We are given two terms and term numbers, so we can solve for the common difference...
101=5+d(25-1)
101=5+25d-d
101=5+24d
96=24d
d=4
So the common difference is 4.
31 it adds up like 1-2-3-4-5-6-7-8-9 so 3+1=4 +2=6+3=9+4=13 and so on
Answer:
7/20 of one shelf in an hour
Step-by-step explanation:
if you think about the problem in numbers out of 100, we know that
- 2/3 of an hour is 40 minutes per hour because 60/3 = 20
- 1/4 of a shelf is 25% of the shelf
In an hour Leland can build 35% of a shelf in an hour or 7/20 of a shelf
Answer:
= -1/2
Step-by-step explanation:
Pick two points
(1,0) and (3,-1)
Then use the slope formula
m = (y2-y1)/(x2-x1)
= (-1 -0)/(3-1)
= -1 /2
