Which number comes next in this series? 1/64, 1/32, 1/16, 1/8, 1/4, 1/2, ?
alexgriva [62]
This is a geometric sequence, with the first term: 1/64

The common ratio is found through the ratio of the first two terms and the second and third term.
\frac{\frac{1}{32}}{\frac{1}{64}} = \frac{\frac{1}{16}}{\frac{1}{32}}
\frac{1}{32} \cdot 64 = \frac{1}{16} \cdot 32

Since there is a common difference of 2, we can generalise this sequence to find the nth term:
T_n = ar^{n-1}
a is the first term, r is the common ratio, and n is the nth term in the sequence.

T_n = \frac{1}{64} \cdot 2^{n-1}
Substituting n = 7, we get:
T_7 = \frac{1}{64} \cdot 2^{7 - 1}
T_7 = \frac{1}{64} \cdot 64
T_7 = \frac{64}{64} = 1

Thus, the next term in the sequence is 1.

m = slope

b = y-intercept

x = (x , y)

y = (x , y)

~

With the given information on top, it means that -8 is your answer.
