Question

what is the 5th term in the sequence d(n)=5/16 (2)^n−1

Answer 1

Answer:

Therefore the 5th term is 5.

Step-by-step explanation:

Given:

Sequence is

$d(n)=\dfrac{5}{16}2^{n-1}$

To Find:

5th term, d(5) = ?

Solution:

$d(n)=\dfrac{5}{16}2^{n-1}$ ....Given

For 5th term put n = 5 then we get

$d(5)=\dfrac{5}{16}2^{5-1}=\dfrac{5}{16}\times 2^{4}\\\\d(5)=\dfrac{5}{16}\times 16=5\\\\\therefore d(5)=5$

Therefore the 5th term is 5.
