Let the first term be \(a\) and the common ratio be \(r\).
The third term is given by \(ar^2 = 1764\).
The sum of the second and third terms is \(ar + ar^2 = 3444\).
We have the equations:
1. \(ar^2 = 1764\)
2. \(ar + ar^2 = 3444\)
From equation 1, \(ar^2 = 1764\).
From equation 2, \(ar + ar^2 = 3444\), substitute \(ar^2 = 1764\):
\(ar + 1764 = 3444\)
\(ar = 3444 - 1764 = 1680\)
Now, divide the two equations:
\(\frac{ar^2}{ar} = \frac{1764}{1680}\)
\(r = \frac{1764}{1680} = \frac{21}{20} = 1.05\)
Substitute \(r = 1.05\) back into \(ar = 1680\):
\(a \times 1.05 = 1680\)
\(a = \frac{1680}{1.05} = 1600\)
The 50th term is given by \(ar^{49}\):
\(1600 \times (1.05)^{49} \approx 17,500\)
