Find the remainder when the sum $2^{2} + 2^{6} + 2^{10} + 2^{14} + \cdots + 2^{110}$ is divided by 10.

 

Grogg multiplies four consecutive integers. What is the sum of all possible values of the units digit of his result?

 

 

Thanks for the help

sumfor(n, 1, 110, 2^(( 2* (2 *n - 1)))) mod 10 = 0

The result appears to be: 0 +4 =4
