Answer 2

Given,

Complete the series,

$\[1, - 8,81,?,15625\]$

Solution,

Observe the series,

$\[\begin{array}{l}{1^2} = 1\\{\left( { - 2} \right)^3} = - 8\\{3^4} = 81\\{\left( { - 4} \right)^5} = - 1024\\{5^6} = 15625\end{array}\]$

Hence the complete series will be $\[1, - 8,81, - 1024,15625\]$
