First, substitute -2 into each equation where there is an <span>x:
</span>(-2)2 -8<span>
</span>(-2) +6
Then multiply the -2 and the 2 in the first equation and add -2 and 6 in the second:
-4 -8
4
Lastly, subtract -4 and 8:
-12
4
Now you have you answers -12 and 4!
This is a geometric sequence with an initial term of 27 and a common ratio of 1/3
This just means that each term is 1/3 the term preceding it.
Any geometric sequence can be expressed as:
a(n)=ar^(n-1), a=initial term, r=common ratio, n=term number in this case:
a(n)=27(1/3)^(n-1)
