What is the general explicit rule for arithmetic sequences?

• $a_n=5xy$

• $a_n=a_0+dn$

• $a_n=d+r$

What is the general explicit rule for geometric sequences?

• $a_n=a_0\left(r\right)^n$

• $a_n=a_0r$

• $a_n=r+d^n$

Use the image above to write the sequence. We will use this image for questions 5-9. Please use pencil and paper to write down answers so that you can refer back. We will be writing the explicit rule.

• 1,2,3,4

• 1,3,5,7

• 2,5,6,10

• 3,8,13,18
