n = 8
the sum to n terms of a geometric sequence is
=
where a is the first term and r the common ratio
here a = 16 and r = = = - 2
= ( 16( 1 - ( - 2 )^n )/1 - (- 2 )) = - 1360
( 1 - (- 2 )^n ) = - 1360
multiply both sides by
1 - (- 2 )^n = - 255
- (- 2 )^n = - 256
)-2)^n = 256
note that and = 256
hence n = 8

Answer:
4a/3
Step-by-step explanation:
7-3 is 4, and the over indicates this will be the numerator.
4a-a simplifies into 3a.
Now, putting together the expression:
4/3a or 4a/3 (If it needs to be rationalised)

It is true that the <span>diagonals of a rhombus divide it into four triangles of equal area.
Since a rhombus has 4 equal sides, and its diagonals are equal, then it means that its triangles are also going to be equal. </span>
Answer:
hundredths place
