There will be 1024 members.
In the first month,total no. of members=4
In the 2nd month,total no. of members=(4x3)+4=16
In the 3rd month,total no. of members=(16x3)+16=64
In the 4th month,total no. of members=(64x3)+64=256
In the 5th month,total no. of members=(256x3)+256=1024

In the first month no. of member=1
In the second month no. of members=1x3+1=4
In the third month no. of members=4x3+4=16
In the fourth month no. of members=16x3+16=64
In the 5th month no. of members=64x3+64=256

At the end of 5th month no of members is 256
They asked to find theTotal no till fifth month
But i think that they wanted to know the members till the end of the fifth month.If there were four members at the end of the 1st month,there will be 1024 at the end of the last month.I request you to calculate again.
