Q. Find the explicit rule for the sequence 6, 10, 14, 18, …
{an} = 2n
{an} = 4n
{an} = n + 4
{an} = 2 + 2n
{an} = 2 + 4n
Q. Find the explicit rule for the sequence 3, 9, 27, 81, …
{an} = 3n
{an} = 3n
{an} = 3n + 3
{an} = 3 + n
{an} = 3!
Q. Find the recursive rule for the sequence 5, 10, 15, 20, …
{an} = an + 5
{an} = (an – 1) + 5
{an} = (an – 2) + 5
{an} = 5(an – 1)
{an} = 5n
Q. Find the recursive rule for the sequence 1, 4, 16, 64, …
{an} = 4(an – 1)
{an} = 4 + (an – 1)
{an} = 4n
{an} = 4n – 1
{an} = 4!
