Answer:
Use the formula for Arithmetic only if it is Arithmetic: a1+ (n-1)d
a represents the first number in the sequence, n represents the number, and d represent common difference
Use the formula for geometric sequence: an=a1r the exponent of r to n-1
an represents the nth term you are trying to find, a1 represents the first number, r represents the common ratio, and n-1 is just the nth term minus 1.
Once you figure out if the sequence is arithmetic or geometric you one of those formulas.
Can you show all the numbers so I could do the math
Answer:
3n+2(n+2)=9n+12
3n+ 2n + 4 = 9n + 12
3n+ 2n +4 - 4 = 9n + 12 - 4
3n + 2n - 9n = 12 - 4
5n - 9n = 8
<u>-4n </u> = <u>8</u>
-4. -4
n. = - 2
As the input is increased by 1.
4 / (1/4) = 4 * 4 = 16
64/4 = 16
1024/64 = 16
So we can see the output factor is increased by a factor of 16.
Hope this helps.
F(x) = 2x+1
f(-4) = 2(-4)+1
= -8+1
= -7
i hope it helps
