-3, -6, -9, -12, -15, -18. You get these by replacing the n with 1, then 2 and so on up to six. So -3 x 1 = -3 -3 x 2 = -6 and so on.

If a is the first term and r the common difference, then the nth term is tn = a * (n-1)r So t16 = a + 15r Then 6*t16 = 6(a + 15r) or 6a + 90r No further simplifiaction is possible.
No because 4/6 = 2/3 in its lowest terms
There are at least two possibilities for this analogy: The second term is half the first, or the second term is the first term minus 10. The first possibility results in 6:3 and second in 6:-4.
! I am having the same problem but mine is 5 times I do not know the answer, but if i find it out ~i shall post it. :) x
It is: 6/8 = 3/4 in its lowest terms
