Ageometric sequence is 3/4,9,108,1296,15,552,186,624.. which is the general term of the sequence?

a(n) = (3/4)(12)^(n-1)

Step-by-step explanation:

The general term of a geometric sequence is a(n) = a(1)(r)^(n-1), where a(1) is the first term, r is the common factor and n is the index (first, second, third, etc.).

Here the first term is 3/4.  By what figure must we multiply 3/4 to obtain the next term, 9?  Dividing 9 by 3/4 results in 12.  The next term, 108, is found by multiplying 9 by 12.  And so on.  Thus, we conclude that the common factor, r is 12.

Thus, the general formula becomes:

a(n) = (3/4)(12)^(n-1).

180 square centimeters

step-by-step explanation:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
