What is the recursive formula for the sequence {−4,−1,2,5,…}?
a. f(1)=−4 and f(n+1)=−4+3
b. f(1)=−4 and f(n+1)=f(n)+3
c. f(1)=−4 and f(n)=f(n+1)+3
d. f(1)=0 and f(n+1)=f(n)−4

The first term is -4, so the recursive formula must start with

Then, as you can see, each term is 3 more than the previous one, so the recursive relation is

which literally means "the next term is the previous one plus three".

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
