F = k / (r^2)
dF/dt = -2k / (r^3) dr/dt
When r = 10^4 km and dr/dt = 0.2 km/sec
dF/dt = -2(10)^3 (0.2) / ((10^4)^3) = -400 / 10^7 = -0.00004 N/s
The gravitational force is changing at the rate of -0.00004 N/s
Let the no be x
4x+9=2x-1
2x=-10
x=-5
<span> f(3) = f(2) + f(1) => 3 + 2 = 5
f(4) = f(3) + f(2) => 5 + 3 = 8
f(5) = f(4) + f(3) => 8 + 5 = 13
Therefore the sequence is 2, 3, 5, 8, 13,.....a Fibonacci sequence.
