2. Iterative process in numbers

1. Add $4$ with the starting number $3$, you will get the number $7$. Now add $4$ with the resultant $7$, you will get the number $11$, again add $4$ with the new resulting $11$, this process goes on.

 

Here, adding $4$ is the iterative process.

 

$3 + 4$, $7 + 4$, $11 + 4$, $15 + 4$, …

 

The sequence obtained is $3$, $7$, $11$, $16$, …

 

 

2. Subtract $3$ from the starting number $99$, you will get the number $96$. Now subtract $3$ from the resultant $96$, you will get the number $93$, again subtract $3$ from the new resulting $93$, this process goes on.

 

Here, subtracting $3$ is the iterative process.

 

$99 - 3$, $96 - 3$, $93 - 3$, $90 - 3$, …

 

The sequence obtained is $99$, $96$, $93$, $90$, …

 

 

3. Multiply the starting number $1$ by $4$, you will get the number $4$. Now multiply the resultant $4$ by $4$, you will get the number $16$. Multiply the new resulting $16$ by $4$; this process goes on.

 

Here, multiplying $4$ is the iterative process.

 

$1 \times 4$, $4 \times 4$, $16 \times 4$, $64 \times 4$…

4. $5$, $50$, $500$, …

 

In this pattern, the values get increased when the number of zeroes increased.

 

 

5. $3$, $9$, $27$, $81$, …

 

This pattern is obtained by generating $3 \times 3^0$, $3 \times 3^1$, $3 \times 3^2$, $3 \times 3^3$…

 

 

6. $1$, $11$, $111$, $1111$, …

 

In this pattern, the values get increased when the number of ones increased.
