Answer:

an = 4n - 1

a1 = 3

a2 = 7 = 3 + 4

a3 = 11 = 3 + 4.2

a4 = 15 = 3 + 4.3

a5 = 19 = 3 + 4.5

.....

=> this is a arithmetic with a1 = 3 and d = 4

=> an = 3 + 4(n - 1) = 4n - 1

hichkok12 [17]

Answer:

50/96

Step-by-step explanation:

I assume the table is:

\left[\begin{array}{cc}Result&Total\\1&15\\2&13\\3&16\\4&17\\5&15\\6&20\end{array}\right]

Even numbers are 2, 4, and 6.  The total number of times she rolled an even number is 13 + 17 + 20 = 50.

So the probability is 50/96.

nadezda [96]

Answer:

I think she should get the Verizon house hold Wifi because when you compare the prices even if Monica doesn't want any extra channels she would still save $15. Even tho the extra channel was $4 for the Comcast when you add it up you get $64 instead when you use Verizon even tho you pay $6 for extra channels you still don't get the amount for the Comcast which you save $13 by getting Verizon with $51.

Write an equation to find the nth term. Then find ₐ₂₄<br> 1, 3, 5, 7,.......
kirill115 [55]

The equation to find the nth term is:

an = a+(n-1)d

Where a is the first term in the sequence, which is 1 and d is the difference, which in this sequence the next term is found by adding 2 to the previous term, so d = 2 and n is the term you want to find.

The equation is:

an = 1 + (n-1)2

a24 = 1 + (24-1)2 = 1 + 23(2) = 1+46 = 47
