A certain arithmetic sequence has this explicit formula for the nth term: a, =11 + (n-1)(4)
The same sequence has this recursive formula:
an = an-1t
What number belongs in the blank space in the recursive formula?

d is the answer

step-by-step explanation:

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14

i think this is a open ended question but i agree with other guy who said you should ask it at english section
