Question

Decode the pattern and obtain the next number in the pattern:
$32,-16,8,-4,2,-1$

• A. $-\frac{1}{2}$
• B. $\frac{1}{2}$
• C. $2$

Answer 1

The correct option is B $\frac{1}{2}$

The given pattern is $32,-16,8,-4,2,-1.$

Here, the subsequent terms are obtained by multiplying $-\frac{1}{2}$ with the previous term.

For example, $32\times -\frac{1}{2}=-16$
The last term is $-1.$

$\therefore$ The next term is $-1\times -\frac{1}{2}=\frac{1}{2}.$

The pattern is $32,-16,8,-4,2,-1,\frac{1}{2}.$
