Answer:
n(n+1)
Step-by-step explanation:
Only the last two formulas work for n=1; only the last formula works for n=2.
<u>For n=1</u>
3n = 3 ≠ 2
n² -1 = 0 ≠ 2
n² +1 = 2
n(n+1) = 2
<u>For n=2</u>
n²+1 = 5 ≠ 6
n(n+1) = 6 . . . . . this last formula works for the given sequence
Answer:7.875 or 7 7/8
Step-by-step explanation:
Y = 15
Because it’s going to every time by 15
The point (4,7) is the only one that can be plugged into the equation and work. in this case when 4 is plugged in as X & Y is plugged in at 7 we get that 7=7, which is a true statement.
