Answer:
11+2n
Step-by-step explanation:
Arithmetic sequence=a+(n-1)d
a=first number
n=nth term
d=difference
a=9
n=?
d=-2
So let's solve
9+(n-1)(-2)
9+(2n+2)
9+2n+2
Collect like terms
9+2+2n
11+2n
So the nth term is 11+2n
Answer:
1.99
Example:
Increase 10 by 99%. 99% of 10 is 9.9 so increased value would be 10 + 9.9 = 19.9
10 x 1.99 = 19.9 ... same answer
Step-by-step explanation:
I think it would be better to have around the middle because there would be people but not to much people
2x(2x+1)(2x-1)... 2x((4x^2)-2x+2x-1)... 2x((4x^2)-1)... (8x^3)-2x ... so the answer would be the last one
