We must find a pattern in the powers of 3:
So, as you can see, both 
and 
end with 1. So, we can generalize as follows:
Since 
, we can deduce that 
ends with 9.
Answer:
y=3x-2
Step-by-step explanation:
Answer:
B) 2^3 x 3 x 5
D) 3^2 x 5^2
Step-by-step explanation:
6 and 10 are composite numbers, not prime, so the answer choices containing those factors can be eliminated. The remaining choices are shown above.
To use the equation we need a1 and d(the common difference).
We have a1 = 57, we need to find d.
93-84 = 9; 84-75=9; 75-66=9; 66-57=9
d = 9
a350 = 57 + (350-1)(9)
a350 = 57 + (349)(9)
a350 = 57 + 3141
a350 = 3198
