Answer:</h3><h3>D</h3><h3 /><h3>
Step-by-step explanation:</h3><h3>
</h3><h3>In a function, an input (x) value should have only one output (y) value.</h3><h3 />
-------------------------------------------------------------------------------------------
<em>Example: (View attached image below). </em><em>Table A</em><em> is a function because each </em><em>x </em><em>value has only 1 </em><em>y</em><em> value. But </em><em>Table B</em><em> is not a function because the </em><em>x value</em><em> of </em><em>4 </em><em>has </em><em>2 y values</em><em>.</em>
the next term is 1 because 64 divide by 16 is 4 which means the geometric sequence is decreasing by 4
5(r - 10) = -51
= 5r - 50 = -51
= 5r = -51 + 50
= 5r = -1
= r = -1/5
r = -0.2
