Answer:
r=3
Step-by-step explanation:
First we add 2 to both sides.
That leaves us with 10r=30
Then we can divide both sides by 10
r=3
The equation would be if y is the numbers in the sequence (like 3, 9, 27) and x is the is the number in the order (like 3 is 1, 9 is 2, 81 is 4) the the equation would be y = 3^x.
Answer:
Step-by-step explanation: it doesn't matter if it says even or odd it's the same formula
Because think if you start with 1 to get 3 you add 2
If you start with 2 to get the next even number you add 2
So it's X+ (X+2)+ (X+4)=93
X is the first # X+2 is the next # X+4 is the 3rd number if you want to check add the numbers to make sure they add up to 93
The smallest of course is X
