It should be two if this is pre calc.
Common difference between the terms is 36
Formula for nth term is 
27th term is 961
Given :
X, 2X + 11 and 4X - 3 are consecutive terms of an arithmetic sequence
To Find:
We need to find the constant difference between the given terms and also find the nth term . Also find the 27th term .
To find the difference , we need to take the difference of consecutive terms

Both the common differences are equal

First term is 25
second term is 2(25)+11=61
Difference is 61-25=26
Common difference = 36
Use nth term formula is

To find 27th term , replace n with 27

Answer:
Happy Tuesday! Here i'll explain it:
Step-by-step explanation:
First you will have to make 2 2/5 into a improper fraction and then subtract the 5/6. after you have done that multiply the 3/4 to the number
Answer:
<u>44 cows and 36 ducks.</u>
Step-by-step explanation:
x is ducks and y is cows.
Assuming both have 1 head each, we can write:
x + y = 80.
Let's assume each x(cow) has 4 legs and each y(duck) has two legs.
Then we can add the numbers of legs:
2x + 4y = 248 legs
Now rearrange x + y = 80 to:
x = 80-y
and substitute:
2x + 4y = 248 legs
2(80-y) + 4y = 248 legs
160 - 2y + 4y = 248 legs
2y = 88 legs
<u>y = 44 [There are 44 cows]</u>
Use this value to find the number of ducks:
x + y = 80
44 + y = 80
<u>y = 36 [There are 36 ducks]</u>
========================
Check:
Do 44 cows and 36 ducks have a total of 248 legs?
4*44 + 2*36 = 248 ?
176 + 72 = 248?
<u>YES</u>
44x + 55x + 77x = 6,464 centimeters.

4x + 5x + 7x = 64 centimeters.
x = 8
Therefore the sides are
4*8 = 32
5*8 = 40 and
7*8 = 56 centimeters
