Answer:
27
Step-by-step explanation:
57 - 3 = 54. 54/2 = 27.
Answer:
a(n) = 20*2.5^(n - 1)
Step-by-step explanation:
Note that 50 is 2.5 times 20, and that 125 is 2.5 times 50. Thus the common factor is 2.5. The formula for the nth term is
a(n) = a(1)*r^(n - 1) => a(n) = 20*2.5^(n - 1)
Answer:
Where's the figure,my friend?
Answer:
-nr+70 <50
or,-nr+70-50 <50-50
or,20-nr <0
or,20-nr-20<-20
or,-nr<-20
or,nr/n<20/n
or,r <20/n
same as
4b-2d=25
or,4b=25+2d
or(4b-25)/2=d
Step-by-step explanation:
we must try to solve equation for answer
