Which represents the recursive formula for the arithmetic sequence  an = 7  3(n1)a_n\ =\ 7\ -\ 3\left(n-1\right)   ?

 a3 = a2  7a_3\ =\ a_2\ -\ 7  

 a3 = a2 × 3a_3\ =\ a_2\ \times\ 3  

 a2 = a1 + 3a_2\ =\ a_1\ +\ 3  

 a2 = a1  3a_2\ =\ a_1\ -\ 3

Which explicit formula represents the sequence: 1, 4, 16, 64, 256... ?

gn = 4 × 1(n1)g_n\ =\ 4\ \times\ 1^{\left(n-1\right)}

gn = 4(n1)g_n\ =\ -4^{\left(n-1\right)}

gn = 4(n1)g_n\ =\ 4^{\left(n-1\right)}

gn = 4 × 1(n1)g_n\ =\ -4\ \times\ 1^{\left(n-1\right)}
