What are the next 4 numbers below? 20, 15, 10, 5, _, _, _, _

Since you are subtracting 5 each time, just continue to subtract 5 and go into negative numbers. So, the next four numbers would be 0,-5, -10, and -15. Hope I helped, could I get brainliest :)

0,-5,-10,-15

Step-by-step explanation:

you are subtracting by 5

(a)

Multiplicative inverse of w will be

(B) As w is same as the product of

So there multiplicative inverse will also be same

Step-by-step explanation:

We have given two complex numbers

and

(a) First we have to find

So

As we know that

So

Multiplicative inverse :

It is that number when multiply with the number which we have have to find the multiplicative inverse gives result as 1

So multiplicative inverse of w will be

Because when we multiply with it gives result as 1

(b) As w is same as the product of

So there multiplicative inverse will also be same
