Solution: Let "l" be the number of bricks in the last step Number of bricks in the 1st step (a) = Number of bricks in the 2nd step = - 2 = 98 d = 98 - = -2 number of steps (n) = 30 (i) t 30 = a + 29d = + 29 (-2) = - 58 = 42 So, we will have 42 bricks in the top most step. After solving for the value of \large {d} d, we can now solve for the value of \large {a {}_1} a1. Multiply equation #1 by − Then add it to equation #2. We get {d=2} d = 2. Plug the values into the alternative arithmetic series formula. This is the system of equations that we are going to solve by the Elimination Method. Solution: a = (a-b)/ (a+b) d = (3a-2b)/ (a+b) - (a-b)/ (a+b) d = [3a - 2b - (a - b)]/ (a + b) d = [3a - 2b -a + b]/ (a + b) d = (2a - b) / (a + b) Sn = (n/2) [2a + (n - 1)d] Apart from the stuff given above, if .
