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:
k= 17
Step-by-step explanation:
51÷3 = k
k = 17
this is the answer
To help you you should find a common denominator and then the fraction that has lower numbers is bigger
