What is the general nth term of the sequence 3, 6, 12, 24?

The general nth term of the sequence 3, 6, 12, 24 can be derived by observing the pattern in the sequence. Notice how each term is formed:

  • The first term is 3.
  • The second term is 6, which is 3 multiplied by 2.
  • The third term is 12, which is 6 multiplied by 2.
  • The fourth term is 24, which is 12 multiplied by 2.

It appears that each term is double the previous term. This is a geometric sequence where the first term a is 3 and the common ratio r is 2.

The formula for the nth term T(n) of a geometric sequence can be expressed as:

T(n) = a * r^(n-1)

Substituting the known values into the formula:

T(n) = 3 * 2^(n-1)

So, the general nth term of the sequence 3, 6, 12, 24 is:

T(n) = 3 * 2^(n-1)
