Write the equation that describes the sequence 20, 28, 36, 44,...

Equation is a(n) = 12 + 8n

Step-by-step explanation:

a(n) = a + (n -1)d

a(n) = 20 + (n - 1)8

      = 20 + 8n - 8

      = 12 + 8n

∴ Equation is a(n) = 12 + 8n

12+8n

Step-by-step explanation:

This is sequence and series

Using the formula,a+(n-1)d

a means the first number

n means the number of progression

d means the difference

a=20

n=?

d=8

Apply the formula

=20+(n-1)8

=20+(8n-8)

=20+8n-8

=20-8+8n

=12+8n

The arithmetic equation is 12+8n
