Most Upvoted Answer
The 7th term of the series 6, 12, 24,.is a 384 b 834 c 438 d none?
Solution:
Finding the Common Ratio (r)
---------------------------
The given series is 6, 12, 24, ...
To find the common ratio 'r', we divide any term by its previous term. Let's take the second and first terms for this purpose:
r = 12/6 = 2
Finding the 7th term (a7)
------------------------
To find the 7th term, we need to use the formula:
an = a1 * r^(n-1)
where a1 is the first term, r is the common ratio, and n is the term number we want to find.
Let's substitute the given values:
a1 = 6 (first term)
r = 2 (common ratio)
n = 7 (term number we want to find)
a7 = 6 * 2^(7-1)
a7 = 6 * 2^6
a7 = 6 * 64
a7 = 384
Therefore, the 7th term of the series 6, 12, 24, ... is 384.
