Answer:
Step-by-step explanation:
A because gross is what they made before everything extra.
-5 - 4 -1 4 11 20 31 subtracting:-
1 3 5 7 9 11 subtractiing:-
2 2 2 2 2
second row is 2 so the rule will contain n^2
so we can write the series as n^2 - 6 , n^2 - 8 , n^2 - 10 etc
the numbers are in arithmetical sequence with a1 = 6 and d = -2
so nth term of our sequence is n^2 - a1 + (n - 1)d = n^2 -2n - 6 + 2
= n^2 - 2n - 4 Answer
Answer:
The awnser is Incorrect
Step-by-step explanation:
So do the Parentheses first (4x2)=8
12-4=8
12-2=10
Now do your multiplcation 8x10=80
Subtract 12-8=4
So the awnser is incorrect
√70 = 8.37
It would be between 8 and 9.
