State whether the following are recurrence relations:
Write the recursive rule from the following descriptions. Let t_n be the nth term.
To find the next term, add 5 to the previous term.
To find the next term, add the two previous terms.
To find the next term, multiply the previous term by negative 1 and then add 7.
To find the next term, subtract one and a half from the previous term.
To find the next term, subtract 6 from the previous term.
To find the next term, multiply the two previous terms.
To find the next term, multiply the previous term by negative 5 and then subtract3.
To find the next term, add three and a quarter to the previous term.
Using the following recursive rules, state the first 5 terms of the sequence in order:
t_{n+1} = 2 t_n, t_1 = 2
a_n = a_{n - 1} + 6, a_1 = - 8
b_n = - b_{n - 1} + 3, b_1 = 0
