Hello :
<span>the nth term of a geometric sequence is :
Un = Up ×r^(n-p) . r is the common ratio
for : p=5 and n= 2
U5 = U2 ×r^3
16 = -2 r^3
r^3 = -8
but : -8 = (-2)^3
so : r = -2
Un = U2 × r^(n-2)
Un = -2 ×(-2)^(n-2)= (-2)^(n-2+1)
</span><span>the nth term of a geometric sequenceis : Un = (-2)^(n-1)</span>
Answer:
The Answer Is E, $6.75
Step-by-step explanation:
Answer:
1.25 inches
Step-by-step explanation:
200 miles/ 50 miles = 5 inch / x
x = (50 x 5) / 200 = 250 / 200 = 1.25
Answer:
p= a +2b
Step-by-step explanation:
Making p the subject of the equation means that we need to arrive at the final answer of p= ____.
a= p -2b
a +2b= p <em>(</em><em>+</em><em>2b</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
p= a +2b
0.3 then 0.13 then 0.19 then 0.31
have a nice day ;)
