Answer:
22
Step-by-step explanation:
the pattern here is to divide the previous number by 3
the first number is 15, divided by 3 to give you the second number:5 ,the second number divided by 3 gives us 5/3
using that principle the first six terms are :
15, 3, 5/3 , 5/9, 5/27, 5/81
(just multiply the denominator by 3)
adding we have
[tex]15 + 5 + \frac{5}{3} + \frac{5}{9} + \frac{5}{27} + \frac{5}{81} = \frac{1820}{81} [/tex]
1820/81 in decimal is 22.4691 to the nearest whole number that is 22.
hope this helps!
