Looking at the figure below, find the 6th term for this pattern: question 3 options: a) 4x - 3 b) x + 9 c) x - 4

21  the nth term is 4n-3

Step-by-step explanation:

1 , 5 , 9

increasing by 4 each time

an = a1 + d(n-1)

where a1 = 1st term

d =common difference

n = term number

a6 = 1 + 4(6-1)

a6 = 1 +4(5)

a6 = 1 + 20

a6 = 21

an = a1 + d(n-1)

an = 1 + 4n-4

an = 4n -3

an = 4n-3

which expression represents the approximate length of bc?
