Answer:

The next term is -1

Step-by-step explanation:

[tex]\left\{\begin{array}{ccc}f(1)=-4\\f(n+1)=f(n)+3\end{array}\right\\\\\text{Put n = 1 to the recursive formula:}\\\\f(1+1)=f(2)=f(1)+3\to f(2)=-4+3=-1[/tex]

Answer:

The next term of the sequence is -1.

Step-by-step explanation:

Given recursive formula,

f(n+1) = f(n) + 3,

For the second term,

Put n = 1,

[tex]f(1+1) = f(1) + 3[/tex],

[tex]\implies f(2) = f(1) + 3[/tex]

Since, f(1) = - 4, ( given )

[tex]\implies f(2) = -4 + 3 = -1[/tex]

Hence, the next term in the sequence would be -1,

Second option is correct.
