Your sequence appears to be geometric with a common ratio of 2. It can be described by
a(n) = (-2 2/3)·2^(n-1)
_____
This can be written in a number of other forms, including
a(n) = (-8/3)·2^(n-1)
a(n) = (-1/3)·2^(n+2)
a(n) = (-4/3)·2^n
Answer = 14/8
Step by step explanation
2 x 7/8
= (2x7)/8
= 14/8
The commutative property states that you can invert the order of the terms of a sum:

So, if you start with

Applying the commutative property you'll get

Simplified: 13/50
Not Simplified: 26/100
