(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A virus give birth to 2 new virus in each second and life span of each virus is 5 seconds.The process of reproduction is continuous until the death of the virus.Initially there is one newly born virus at time t=0.Find the total number of live viruses just after 10 seconds.

2. Relevant equations

number of viruses born - number of viruses dead

3. The attempt at a solution

Number of born viruses = 1+2+4+8+...+1024

Number of viruses dead = 0x4+(1+2+4+...+64)

there fore, answer = 2^{7}+2^{8}+2^{9}+2^{10}

but the given answer is 3^{5}(3^{5}-1)

Nowhere near!!!!

pls help......
