The 3rd and 4th terms of an arithmetic sequence are 13 and 18, respectively. What is the 50th term of the sequence?

in an arithmetic sequence, the nth term is the first term +(n-1)times the difference

the difference between the 3rd and 4th term is 18-13=5, so d=5

now we need to find out the first term: 13=a1+(3-1)d => a1=3

the 50th term is a1+(50-1)d=3+49*5=248

the  

Step-by-step explanation:

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%
