Answer: 2n^2+3n-4
1st differnce is 3, 7, 11, 15
2nd differnce is 4
so its 2n^2
we compare it to teh 2n^2 sequence
2 8 18 32 50
-1 2 9 20 35
difference is 3, 6, 9, 12,15
so it is 3n-4
The answer is 3 and 8 twelves
Answer: A
Explanation: this is just something u can eye ball
Every proportional relationship is an equation like y = a number times 'x'. When you graph that equation it's a straight line that goes through the origin and every point on the line satisfies the equation. Line B is the only graph that looks like that. The others all have a piece of a proportional relationship. Their bottom pieces are proportional relationships but then they break and the top pieces are not.
Two prime numbers greater than 25 and less than 35.
Let p be a prime that satisfies
25 ≤ p ≤ 35.
The set of prime numbers:
P = {2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, ... }
There are only two prime numbers greater than 25 and less than 35:
Answer: {29, 31}.
