Question

Study the pattern and write the next two steps:

$$\begin{gathered} 1\times 8+1=9 \\ 12\times 8+2=98 \\ 123\times 8+3=987 \\ 1234\times 8+4=9876 \\ 12345\times 8+5=98765 \end{gathered}$$

Answer 1

If we observe the pattern, we can see that numbers are increasing on left hand side. Similarly on the right hand side as well numbers are increasing in a decreasing pattern.

Following the same pattern, next steps will be

$$\begin{gathered} 123456\times 8+6=987654and \\ 1234567\times 8+7=9876543 \end{gathered}$$

Hence the final pattern will be as follows:

$$\begin{gathered} 1\times 8+1=9 \\ 12\times 8+2=98 \\ 123\times 8+3=987 \\ 1234\times 8+4=9876 \\ 12345\times 8+5=98765 \\ 123456\times 8+6=987654 \\ 1234567\times 8+7=9876543 \end{gathered}$$
