So pattern A goes from 1, to 2, to 4, to 8, to 16, to So it looks like pattern A, to go from the first term to the second term, we multiplied by 2.
And then to go from the second to the third term, we also multiplied by 2. And we just keep multiplying by 2. And we just keep doing that. Now let's think about what's going on with pattern B. So pattern B is the second number in each of these pairs. And it's just always 3. So there's a couple of ways you can think about it. You could just say, pattern B's always 3.
You could say pattern B starts at 3, and we're just adding 0 every time. Or you could say that pattern B starts at 3, and we are multiplying by 1 every time. Either of those would give you just 3 showing up over and over again.Top 100 Thomas Sanders Vines (w/Titles) Funny Thomas Sanders Vine Compilation 2017
So now that we've looked at these pairs, we show the corresponding terms for pattern A and pattern B, let's look at the choices here and see which of these apply. In pattern A, you can get from any term to the next by multiplying by a constant number.
Well, that looks right. We go from the first term to the second term by multiplying by 2. Then we multiply by 2 again to get to the third term. Then we keep multiplying by 2. So that constant number that we're multiplying by to get to the next term is 2.
So this looks right. The next pair should be 52 comma 3. So let's think about this.

If we keep doubling for pattern A-- so this is going to be times 2. And then if we'd say that this is 1 times the previous term, we're just going to get a 3 again. So it should be 64 comma 3 should be the next one. They say the next pair should be 52 comma 3. So that's not right.
Interpreting relationships in ordered pairs
If we graph the pairs, the points will be on the same line. So let's think about that a little bit. Let's think about that. So this is my vertical axis. This is my horizontal axis. On the horizontal axis, I will graph pattern A. And on my vertical axis, I will graph pattern B. Pattern A goes all the way up to So, we can only compare the timing of branching events that occur on the same lineage same direct line from the root of the treeand not those that occur on different lineages.
Some tips for reading phylogenetic trees You may see phylogenetic trees drawn in many different formats. Some are blocky, like the tree at left below. Others use diagonal lines, like the tree at right below.
You may also see trees of either kind oriented vertically or flipped on their sides, as shown for the blocky tree. You may want to take a moment to convince yourself that this is really the case — that is, that no branching patterns or recent-ness of common ancestors are different between the two trees. The identical information in these different-looking trees reminds us that it's the branching pattern and not the lengths of branches that's meaningful in a typical tree.
So just like the two trees above, which show the same relationships even though they are formatted differently, all of the trees below show the same relationships among four species: Figure 3 by Robert Bear et al.
So far, all the trees we've looked at have had nice, clean branching patterns, with just two lineages lines of descent emerging from each branch point.
In general, a polytomy shows where we don't have enough information to determine branching order. Where do these trees come from? To generate a phylogenetic tree, scientists often compare and analyze many characteristics of the species or other groups involved. To build accurate, meaningful trees, biologists will often use many different characteristics reducing the chances of any one imperfect piece of data leading to a wrong tree.
Still, phylogenetic trees are hypotheses, not definitive answers, and they can only be as good as the data available when they're made. Trees are revised and updated over time as new data becomes available and can be added to the analysis. This is particularly true today, as DNA sequencing increases our ability to compare genes between species.
