# We already know the rule for the pattern of letters L, C and F. Some of the letters from Q.1 (given above) give us the same rule as that given by L. Which are these? Why does this happen?

**Solution:**

We will use the concept of algebra to answer the given questions.

The rule for the pattern of letter L is the same as the rule for letters T and V that is 2n.

Here 'n ' represents the number of letters.

The rules are the same because the number of sticks required in the formation of the above letters is the same i.e 2.

∴ These letters give the same rule as that given by L

The rule for the pattern of letter C is the same as the rule for letter Z and U i.e 3n as these letters have three matchsticks.

## We already know the rule for the pattern of letters L, C and F. Some of the letters from Ql. (given above) give us the same rule as that given by L. Which are these? Why does this happen?

**Summary:**

The rule for any letter is the product of a number of matchsticks needed to form the letter and the variable n, where n = number of letters. The rule for the pattern of letter L is the same as rule for letters T and V that is, 2n whereas the rule for the pattern of letter C is the same as rule for letter Z and U, that is, 3n.
