How would i do this problem: It says
The total number of lights in a triangular rig with n rows is given by the function T(n) as given. Find the number of lights in triangular rigs with 1 to 10 rows.
T(n)=1/2n^2+1/2n

Best ResponseYou've already chosen the best response.2I would use the formula. I'll do T(2). Pay attention! T(2) = 0.5 * 2*2 + 0.5*2 = 2+1 = 3 (which matches the picture) try T(3) = 0.5*3*3 + 0.5*3 this is multiply and add.

Best ResponseYou've already chosen the best response.0A lighting rig is a large bank of lights that creates lighting effects at concerts and sporting events. A company makes rigs with lights arranged in polygonal patterns. For example, a triangular rig may have 1, 3, 6, 10, or 15 lights, depending on its size. Analyze and answer the related problems. The total number of lights in a triangular rig with n rows is given by the function T(n) as given. Find the number of lights in triangular rigs with 1 to 10 rows. T(n)=1/2n^2+1/2n a. 1, 3, 6, 10, 15, 22, 29, 37, 46, 56 b. 1, 3, 6, 10, 15, 20, 25, 30, 35, 40 c. 1, 3, 6, 10, 13, 16, 20, 23, 26, 30 d. 1, 3, 6, 10, 15, 21, 28, 36, 45, 55 wud it be D??
