Answer 2

Given:

Series: 50, 40, 30, 20, 10, 0,​ ?

To find:

The last number

Solution:

The required last term is -10.

We can obtain the required term by subtracting 10 from each of the terms progressively.

We see that each term is reduced by 10 to obtain the next term.

The first term=50

The second term=50-10=40

The third term=40-10=30

The fourth term=30-10=20

The fifth term=20-10=10

The sixth term=10-10=0

We will further subtract 10 from 0 to calculate the required last term.

The last term=0-10= -10

Therefore, the required last term is -10.
