Answer:
93
Step-by-step explanation:
First differences increase by 4 each time. The given numbers are a quadratic sequence that can be described by 2n² -2n +9. The 7th term would be 93.
_____
First differences are ...
13-9 = 4, 21-13 = 8, 33-21 = 12, 49-33 = 16, 69-49 = 20
Second differences are ...
8-4 = 4, 12-8 = 4, 16-12 = 4, 20-16 = 4
When second differences are constant, the sequence can be represented by a second-degree polynomial function. The leading coefficient is half the value of the second differences.
Just pick a number
i’ll pick 2
and solve the equations
1. 6(2+12)
12+72
84
2. 6(2)+12
12+12
24
3.3(2(2)+4)
3(4+4)
3(8)
24
your answer is D
expressions 2 and 3 are equivalent
We have a work problem right here. We can use knowledge on ration and proportion to answer this type of problem. We do as follows:
1 job / 2 hours + 1 job / 3 hours = 1 job / time it takes for both when working together
time it takes for both when working together = 1.2 hours
The answer is d because if you compare feet to yards 3 feet= 1 yard so divide 630 and 285 by 3 and then multiply them which ends up in 19,950. Your Welcome!
