\(\begin{array} { r c l c r} 1 & \times & 8 & = & 8\\ 11 & \times & 88 & = & 968\\ 111 & \times & 888 & = & 98568\\ 1111 & \times & 8888 & = & 9874568\\ 11111 & \times & 88888 & = & 987634568\\ 111111 & \times & 888888 & = & 98765234568\\ \end{array}\)

 

What is the value of  1111111*8888888, the next line in the series?

Looking for a pattern, we find that the numbers are decreasing in two ways.

First, starting from the very right (the number 9) to the left.

Second, decreasing from left to right starting from the number 5. 

So we can see through this pattern that the next term is 9876541234568.
