Question

Look for the pattern and take this forward.

$\begin{array}{rcccr}\left(0\times 9\right)& +& 1& =& 1\\ \left(1\times 9\right)& +& 2& =& 11\\ \left(12\times 9\right)& +& 3& =& 111\\ \left(123\times 9\right)& +& 4& =& \underline{}\\ \left(1234\times 9\right)& +& 5& =& \underline{}\\ \left(12345\times 9\right)& +& 6& =& \underline{}\end{array}$

Answer 1

$\begin{array}{rrrcr}\left(0\times 9\right)& +& 1& =& 1\\ \left(1\times 9\right)& +& 2& =& 11\\ \left(12\times 9\right)& +& 3& =& 111\\ \left(123\times 9\right)& +& 4& =& \underline{1111}\\ \left(1234\times 9\right)& +& 5& =& \underline{11111}\\ \left(12345\times 9\right)& +& 6& =& \underline{111111}\end{array}$
