1 x 1=1

11 x11= 121

111 x 111 = 12321

  ?      = 1234321

 

Given:

Pattern: 

$$\begin{gathered} 1\times 1=1 \\ 11\times 11=121 \\ 111\times 111=12321 \\ ?=1234321 \end{gathered}$$

We have to find the value for $?$

Now as we can see in the pattern it shows the multiplication of two numbers or we can say the square of two numbers.

Firstly it is $1\times 1=1$ then $11\times 11=121$ then $111\times 111=12321$

Now, after three 1's, next will be four 1's, i.e

Next in the pattern will be $1111\times 1111=1234321$.

Therefore, Option A is the correct answer.
