Consider the following sequence: 7, 11, 15, 19, 23, . . .
The common difference is
What is the Explicit equation for the sequence?
t(n) = n +

What is the 20th term?

Step-by-step explanation:

This is an arithmetic progression.

It starts at 7 and keeps on adding 4.

The common difference is 4

The explicit equation is

t_n = a + (n - 1)*d

a =  7

d = 4

t_n = 7 + (n - 1)*4

t_n = 7 + 4n - 4

t_n = 4n + 3

t_20

t_20 = 4*20 + 3

t_20 = 83
