Answer:
a₄=8n+1= -39.
Step-by-step explanation:
1) if a₁=3n; a₃=5n-6 and a₅=11n+8, then it is possible to calculate the difference according to 0.5(a₅-a₃)=0.5(a₃-a₁). Then
2) 0.5(11n+8-5n+6)=0.5(5n-6-3n); ⇔ 6n+14=2n-6; ⇔ n= -5.
3) if n=-5, then the 4th term is:
![a_4=\frac{a_5+a_3}{2}; \ = > \ a_4=\frac{11n+8+5n-6}{2}=8n+1;](https://tex.z-dn.net/?f=a_4%3D%5Cfrac%7Ba_5%2Ba_3%7D%7B2%7D%3B%20%5C%20%3D%20%3E%20%5C%20a_4%3D%5Cfrac%7B11n%2B8%2B5n-6%7D%7B2%7D%3D8n%2B1%3B)
or a₄=-39.
Answer:
Just divide the numbers by 10 and then multiply the quotient by 2. hope this helped
Answer:
The correct answer is D) 7+(3+1)=(7+3)+1
Step-by-step explanation:
The associative property of addition states that it doesn't matter how you group numbers inside of parenthesis, it gives you the same answer. So even though the groupings are different in that example, the answer is still the same.
