Expert Solution

Consider the following sum:

7Σk=12k

 

The lower limit of above summation is k = 1 and upper limit is k = 7

 

To find the sum of values of function 2k from k = 1 to k = 7, substitute k = 1, 2, 3, 4, 5, 6, 7 in the function 2k and then find the sum.

7Σk=12k = 21 + 22 + 23 + 24 + 25 + 26 + 27

      = 2 + 4 + 8 + 16 + 32 + 64 + 128

      = 254

 

Therefore, the above summation is equal to 254.

Therefore, the above summation is equal to 254.
