Hey All;

Let's get directly looking at our **Math Brain Teasers 12**; solve the following grid puzzle. Observe the number grid carefully and try finding out the number that should replace the question mark.

**Hint:: ** this grid puzzle is not at all complicated. It involves simple logic and involves simple mathematics. All; I can say is that you just need to look/observe a pattern that is being formed. Once you are able to see the pattern, the answer will directly crop up.

##### Math Brain Teasers 11:: Patterns Within the Triangle? - Solved with Explanation

Yes; in order to solve this Triangle puzzle. We need to know and have some understanding of **PASCAL'S TRIANGLE**. Let's have a look at the steps required to reach the answer...

Step 1. First of all; just observe that there is 1's along sides i.e.

`1 1 1 & so forth...`

Step 2. Now to get the other numbers. We add two numbers that are above.. i.e.

we add 1 + 1 to get 2 in the third row. Therefore in the fourth row, we add 1 + 2; 2+ 1 to get 3.

So, if you observe carefully this is happening all across.

```
1
1 1
1 2 1
1 3 3 1 & so forth...
```

Therefore the correct answer to our **Math Brain Teasers 11 ::** Patterns Within the Triangle? = **6** followed with the next line being generated as follows::
