NARAYAHConsider a sequence whose first five terms are: 0, -2,-8, -18, -32Which function (with domain all integers n 1) could be used to define and continue this sequence?@®©f(n)= - 2n2f(n) = -(n)-1f(n) = -2(n-1)1=-1fof(n) = -2(n-1)?

Answer:None of the given functions can be used to define this sequence.Step-by-step explanation:Here the given sequence is 0, -2, -8 , -18 , -32, ....The given function are [tex]f(n) = -2n^{2} , f(n) = -n -1 , f(n) = -2(n-1)[/tex]Now, check for each functions: 1) [tex]f(n) = -2n^{2}[/tex]for  n = 1 , [tex]f(1) = -2(1)^{2}   = -2[/tex] ≠ 0Hence, the given function DO NOT satisfy the sequence.2) [tex]f(n) = -n -1 [/tex]for n = 1, f(0) =  -1 -1  = -2 ≠ 0Hence, the given function DO NOT satisfies the sequence.3) [tex]f(n) = -2(n -1) [/tex]for  n = 1 , f(1) = -2(1 -1)  = -2 x 0   = 0for n = 2 , f(2) = -2(2 -1)  = -2 x 1   = -2for n = 3,  f(2) = -2(3 -1)  = -2 x 2    =  -4   ≠ -8Hence, the given function DO NOT satisfies the sequence.
