A coefficient is a number multiplied by a variable.

In this case, our variable is a.
The coefficient is 12.

(PS: The +5 that isn't being multiplied by a variable is called a constant)

Why does it takes 3 copies of 1/6 to show the same amount as 1copy of 1 / 2
Veseljchak [2.6K]
Because 1/2 ≠ 1/6.

We know that 1/6 < 1/2, so we can set up an equation to see how many copies are needed for them to be equal.

(1/6)x = 1/2
[(1/6)x] × 6 = [1/2] × 6
x = 6/2 = 3

This equation shows that 1/6 × 3 = 1/2, therefore we need 3 copies of 1/6 to equal 1 copy of 1/2.

What is the explicit rule for the sequence:<br> 11, 22, 44, 88...
andriy [413]

Answer:

<u>Geometric Progression</u> is the explicit rule for the given sequence: 11, 22, 44, 88...

First term (a) = <u>11</u>

Common ratio (r) = 22/11 = 44/22 = 88/44 = <u>2</u>

Formula used in Geometric Progression is :---

\boxed{a_n = a {r}^{(n - 1)}}✓\\

where, 'n' is the required term

A certain arithmetic sequence has this explicit formula for the nth term:
swat32

Answer:

4

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given

a_{n} = 11 +(n - 1)4 , then

d = 4

The recursive formula allows a term in the sequence to be found by adding d to the previous term, thus

a_{n} = a_{n-1} + 4
