Question

write a program to display sum of following series i.e sum of factorial of odd series multiple with x where power of x is squre of crossponding number X^1*1!+X^9*3!+.....X^n2*n!

Answer 1

In the future, please state the language you are using. I'll try to throw together some pseudocode for you...

Answer 2

#initialize a sum to zero and a variable for the factorial term to one
#get a value for x (by user input I presume)
#while there are still more terms (i.e. we have not yet reached n)
#add the current term to sum
#increment the factorial term by 2
#output the sum
