I'm not sure how to write the rule, but every time you add one more to the sum of the last two. First, you add 1, then 2, then 3. 1+1=2 2+2=4 4+3=7 7+4=11 and so on. I hope this helps!

What is the multiplicative inverse of c/d? Explain how a number is related to its multiplicative inverse.

Lana71 [14]

Answer:

$\frac{d}{c}$

Step-by-step explanation:

The multiplicative inverse of a number n is $\frac{1}{n}$

The product of the number and its multiplicative inverse = 1

n × $\frac{1}{n}$ = 1

Thus the multiplicative inverse of $\frac{c}{d}$ is

$\frac{1}{\frac{c}{d} }$ = $\frac{d}{c}$
