Answer:
24.61
Step-by-step explanation:
first you have 7 and 3 and since 2x3 is 6 you get 2 and the remain will be 1 you then have your 3 and the closest one is 4 since 4x3 is 12 you subtract 13-12 which gives you 1 you bring your 8 down and will give you 18 and 6x3 is 18 so gives you the six then lastly is 3 which 3x1 is 3 so gives you the one hopefully that makes sense
-16.8 * -10= 168 is the answer
Answer:
2.57
Step-by-step explanation:
The common ratio of this sequence is ...
(1/3)/(3/15) = (1/3)/(1/5) = 5/3
Each additional term is 5/3 times the previous one, so the 8th term will be (5/3)^4 times the 4th term (the last one given). It is ...
(1/3)·(5/3)^4 = 625/243 ≈ 2.57
_____
The generic n-th term (an) is ...
an = a1·r^(n-1)
where a1 is the first term and r is the common ratio. We can make use of this formula to find the 8th term:
a8 = (27/375)·(5/3)^7 = (3^3/3^7)·(5^7/(3·5^3)) = 5^4/3^5 = 625/243 ≈ 2.57
