What is a formula for the nth term of a given sequence
-12,-16,-
an = -12(-4)^n
a^n = -12 - 4 (n+1)
an = -8 - 4n
an = -12(-4)^n-1

Step-by-step explanation:

The given sequence is

-12,-16,-20...

The first term of this sequence is .

The common difference is

The nth term of this arithmetic sequence is;

We substitute the values for the first term and the common difference to obtain;

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
