Explanation

The 5th term of the given geometric progression (G.P.) is 48. The sequence is 3, 6, 12, ...

The common ratio is 2 (6/3 = 2, 12/6 = 2).

Using the formula for the nth term of a G.P., a_n = a * r^(n-1),

where a is the first term and r is the common ratio, the 5th term (a_5) is 3 * 2^(5-1) = 3 * 2^4 = 3 * 16 = 48.
