I need to know if the function is arithmetic or geometric define a recursive function f(n) for the sequence in terms of f(n-1)? or if the function is arithmetic or geometric define an explicit function f(n) for the sequence in terms of n

Consider the following sequence where f (1) = 28. 28, 40, 52, 64, ... Identify the type of sequence. Arithmetic O Geometric O Neither arithmetic nor geometric There is not enough information given If the function is arithmetic or geometric, define a recursive function f (n) for the sequence in terms of f (n - 1); otherwise, enter None. If the function is arithmetic or geometric, define an explicit function f (n) for the sequence in terms of n; otherwise, enter None. O Not quite DELL
