Find the first four terms of the sequence given the following. a, =4(3)"-", n= 1, 2, 3.

Para encontrar los primeros cuatro términos de la sucesión, se sustituye el valor de \( n \) y se calcula cada término.

\text{Para } n = 1: a_1 = 4(3)^{1-1} = 4(3)^0 = 4 \cdot 1 = 4
\text{Para } n = 2: a_2 = 4(3)^{2-1} = 4(3)^1 = 4 \cdot 3 = 12
\text{Para } n = 3: a_3 = 4(3)^{3-1} = 4(3)^2 = 4 \cdot 9 = 36
\text{Para } n = 4: a_4 = 4(3)^{4-1} = 4(3)^3 = 4 \cdot 27 = 108

a_1 = 4
a_2 = 12
a_3 = 36
a_4 = 108
