Find an explicit rule for the nth term of the sequence. 3, -12, 48, -192,

Step-by-step explanation:

Given sequence :

Here, First term

Second term

and  Ratio=

Third term

Ratio=

Fourth term

Ratio=

Thus, the given sequence is geometric sequence with the common ratio r = -4.

The explicit rule for for the nth term in geometric sequence is given by

Then the explicit rule for the nth term of the given sequence will be :-

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
