a_n=5(n+1)!

Assume n starts at the value, 1.

a_1=5(1+1)!
a_1=5(2)!
a_1=10!

a_2=5(2+1)!
a_2=5(3)!
a_2=15!

a_3=5(3+1)!
a_3=5(4)!
a_3=20!

a_4=5(4+1)!
a_4=5(5)!
a_4=25!

[a_n] = [10!~, 15!~, 20!~, 25!]

What group of numbers does -2 belong to?
Marizza181 [45]
Answer: Integers and Rational Numbers

Explanation: -2 is an integer because integers include positive an negative numbers. It would not be a whole number or a Naural number because both of those sets only include positive numbers. Here’s a better explanation:

Natural numbers: Natural Numbers are like (1,2,3....). They only include positive numbers. Therefore, -2 does not belong in this category.

Whole Numbers: Whole Numbers are like (0,1,2,3....). They include all the natural numbers with 0. Therefore, -2 does not belong in this set.

Integers: Integers include both positive and negative numbers. They are like (-3,-2,-1,0,1,2,3....). Since they both have positive and negative numbers, -2 would belong in this set.

Rational Numbers: Rational Numbers include ALL the sets that were described. (Natural, Whole, Integer). Since this set also includes positive and negative numbers, -2 would belong in this set.

So, -2 belongs in Integers and Rational Numbers

Factorise 12u-uv please help lol
max2010maxim [7]

Answer:

u(12-v)

Step-by-step explanation:

12u and -uv both have a factor of <em>u </em>in common, so we can pull it out to give us the factored expression u(12-v).

<em>Note on factoring:</em>

<em>Remember, it's just using the distributive property in reverse! We can get our original expression back by distributing the u to the 12 and the -v.</em>

For the following geometric sequence find the recursive formula: {-1, 3, -9, ...}.
vredina [299]
First term (a1) is -1

recursive formula goes like this

a_n is the nth term
a_{n-1} is the term before that

we normally have a_n=f(a_{n-1})

we see each term is multipying by -3 to get next one


so that would be
a_n=-3*a_{n-1} where a1=-1


the 3rd option is correct except that it is the explicit formula

so answer is 2nd one
