F(n)=−11+22(n−1), left parenthesis, n, right parenthesis, equals, minus, 11, plus, 22, left parenthesis, n, minus, 1, right pare

prisoha [69]

Answer:

$a_1 = -11\\\\a_n = a_{(n - 1)} + 22$

Step-by-step explanation:

An arithmetic sequence is generally given as:

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

where a = first term and f(n) = nth term, d = common difference

The explicit formula given is:

f(n) = 11 + 22(n - 1)

The recursive formula is made of two statements, the first term and the formula showing how successive terms are related.

Mathematically, it is given as:

$a_1 = a\\\\a_n = a_{(n - 1)} + d$

Therefore, the recursive formula is:

$a_1 = -11\\\\a_n = a_{(n - 1)} + 22$
