Answer:
Lol, isn't that just -2?
Step-by-step explanation:
I think you can just add those up.
the answer is 4
because: 6 + 25 = 31 - 7 = 24 ÷ 6 = 4
Answer:
Because each term of the sequence generates numbers with more than 1 and itself as dividers
Step-by-step explanation:
Just for the sake of correction.

1) Let's consider that
n! =n(n-1)(n-2)(n-3)...
2)And examine some numbers of that sequence above:

Every Natural number plugged in n, and added by two will a be an even number not only divisible by two, but in some cases by other numbers for example,n=4, then 4!+2=26 which has four dividers.
3) Similarly, the same happens to
and 
Where we can find many dividers.
There's an example of a sequence, let's start with a prime number greater than 1
Let n=11

That's a long sequence of consecutive composite numbers, n=11.

$2.45. Thats it i think but idk the equasion part. Sorry
Answer:
12.1
Step-by-step explanation:
Let the number be " x ".
The sum of a number and 2.6,
x + 2.6
1/3 times the sum of a number and 2.6
1/3 * ( x + 2.6 ) = ( x + 2.6 )/3
1/3 times the sum of a number and 2.6 is 4.9
( x + 2.6 )/3 = 4.9
x + 2.6 = 4.9 * 3
x + 2.6 = 14.7
x = 14.7 - 2.6
x = 12.1
Therefore,
the number is 12.1
