Answer:
x = 6
Step-by-step explanation:
Love proportions!
3x+2(x+6) = 35(21)
21(3x+2) = 35(x+6)
63x + 42 = 35x + 210
28x = 168
x = 6
Answer:
Step-by-step explanation:
I don’t know why they bother teaching recursive formulas as the explicit is almost always used :)
For 2,9,16,23...
Recursive is a(n+1)=an+7
Explicit is an=2+7(n-1)
(or more neatly an=7n-5)
For 2,14,98,686...
Recursive is a(n+1)=7an
Explicit is an=2(7^(n-1))
(or (2/7)7^n )
Answer: 4,5
