The sum can be calculated directly by evaluating each term in the series and then adding them together. The series is: (1+4) + (2+4) + (3+4) + (4+4) + (5+4) + (6+4) + (7+4) + (8+4) = 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 68.

Evaluate the Sum ∑i=18(i+4)\sum _ { \mathrm { i } = 1 } ^ { 8 } ( \mathrm { i } + 4 )∑i=18​(i+4)

Evaluate the Sum $\sum _ { \mathrm { i } = 1 } ^ { 8 } ( \mathrm { i } + 4 )$
