Sveta_85 [38]

Answer:

That's 2635249153387078 pounds or  1317624576693.5 tons

Step-by-step explanation:

The series is 2^(n-1) where n=1,2,3,4,...,62,63,64

 

We can adjust the index and write it as 2^n where n=0,1,2,3,4,...,61,62,63

 

The sum of the geometric series is:

 

 a1 * (1 - r^n)

------------------  

         1-r

 

where r is the common ratio in this case 2,

a1 is the first term, in this case 1,

and n is the number of term, in this case 64

 

 

1 * (1 - 2^64)

----------------  = 18446744073709551615

 1 - 2

 

Dividing that by 7000

That's 2635249153387078 pounds or  1317624576693.5 tons
