What is the gcf of 19 and 22

Mrrafil [7]

The GCF would simply be 1 because 19 is a prime number. This means that the only factors of 19 are 1 and 19, while the factors of 22 would be 1, 2, 11, and 22. The only factor they share is 1, so their greatest common factor is 1.

Given a sequence is defined by the explicit definition tn=n^2+n.... (questions attached)

s2008m [1.1K]

Question 1: The correct answer is Option 3: 20

Question 2: The correct answer is Option 3: 27

Step-by-step explanation:

We put the term number as value of n in explicit formula to find the term.

<u>Question 1:</u>

Given

$t_n=n^2+n$

To find t4, we will put t=4 in explicit formula

$t_4=(4)^2+4\\t_4=16+4\\t_4=20$

The correct answer is Option 3: 20

<u>Question 2:</u>

Given, the explicit formula

$t_n=2^n-n$

We have to find the 5th term, putting n=5 in the explicit formula

$t_5=2^5-5\\=32-5\\=27$

The correct answer is Option 3: 27
