## anonymous 4 years ago How can I simplify this series? 2^0 + 2^1 + 2^2 + 2^3 + ........ + 2^100

1. anonymous

Do you know geometric progression?

2. Akshay_Budhkar

yea u can just plug in your values in the summation formula of geometric sequence

3. anonymous

Or you could derive it on your own ;)

4. Akshay_Budhkar

Lol

Akshay, this problem is too easy for you, go and solve the the one I posted :P

6. Akshay_Budhkar

hehe

7. anonymous

The answer for this one is $$2^{101}-1$$

8. Akshay_Budhkar

$2^{101}-1 \over (2-1)$ to be precise using the formula

9. anonymous

Can you show me the formula please?

I do not know geometric progression. I'm sorry. I do really like FoolForMath's picture. It's funny.
