Answer:
a(n) = 12 * (13)^(n-1)
Step-by-step explanation:
First step is to determine what's the scale/multiplication factor between each term:
156 / 12 = 13
2028 / 156 = 13
So, since we got 13 between 1st, 2nd and 3rd term, we can be confident it's the right multiplication factor.
an would be the first term (12) multiplied by a factor of 13. So,
If we try for n > 1, we have
a(2) = 12 * (13)^(2-1) = 12 * 13 = 156
a(3) = 12 * (13)^(3-1) = 12 * 13² = 12 * 169 = 2028
It matches!
Answer:
5y-9x/xy
Step-by-step explanation:
Answer:
5/4
Step-by-step explanation:
Lets suppose a quantity A that has a value of x
A = x
25% of A is = x/4
now adding this 25% to get 25% increase in the original value
A' = x+ x/4
A' = 5x/4
A' = 5*A/4
This means that , in order to increase the value by 25% in a single step we must multiply the the original value by 5/4.
Answer:
32.5
Step-by-step explanation:
there are 4 rows
1 = 3
2 = 5
3 = 2
so there is 10 numbers
We go for the middle number which is 2-3 so the answer must be 32.5.
We know it is between 2-3 as the same as 1-10
1,2,3,4,5, ------ 6,7,8,9,10
So the imput numbers are listed 2 + 3 in your stem diagram where so 5 + 6 would be in the explanation. As 10 +1 = 11 then 11/2 = 5.5 - this means 5.5 = 32.5 as 33 would be the 6.
1/5...
This question should be relatively easy for a high schooler...
