Answer:

D) 262,144

Step-by-step explanation:

The given sequence is given explicitly as:

A_n =  {4}^{n - 1}

We want to find the tenth term of this sequence.

We substitute n=10 to get:

A_ {10}=  {4}^{10 - 1}

Simplify the exponent

A_ {10}=  {4}^{9}

Simplify the power

A_ {10}=  262144

Therefore the 10th term is 262,144

mean = sum of all observations / total no. of observations

= 7+9+10+6+8+12+5+11+48+13 / 10

= 12.9

median = middlemost no. after arranging in ascending order

= 5,6,7,8,9,10,11,13,48

=9 and 10

=9+10 / 2

= 19 / 2

= 9.5
