If a1 + A2 = 2, A3 + A4 = 8, then S8 is equal to?

A1 + A2 = a1 + a1q = A1 (1 + Q) = 2 1A3 + A4 = a1q ^ 2 + a1q ^ 3 = a1q ^ 2 (1 + Q) = 8 22 divide by 1 to get Q ^ 2 = 4q = ± 2, and substitute into 1 to get A1 = 2 / 3 A1 = - 2 (rounding off q = - 2) S8 = A1 (Q ^ 8-1) / (Q-1) = 2 / 3 * (2 ^ 8-1) / (2-1) = 170

The convoy transported a batch of relief materials to the disaster area, traveling 60 kilometers per hour when going, reaching the disaster area in 6.5 hours, and traveling 78 kilometers per hour when coming back. How long can it take to return
Go back to the place of departure and explain what must be proportional to who

The return time is t
60*6.5＝78*T
T＝5
Return to the departure point in 5 hours
The reason I'm going to make this simple equation is to make you understand what inverse proportion is
When the distance is fixed, the speed and time must be in inverse proportion
