Question

Eve's sequence decreases by 2 hundreths each time. she picks a number to start with. what is the difference betwen her 3rd and 6th number?

Answer 1

Answer: 0.06

Step-by-step explanation:

Given

Eve's number decreases by 2 hundredths each time i.e. $0.02$

Difference between 3rd and 4 th number is $0.02$, while the difference between 3 rd and 5 th is double the previous i.e. $2\times 0.02=0.04$

So, the the difference between the 3 rd and 6 th number is three time the difference

$\Rightarrow 3\times 0.02\\\Rightarrow 0.06$
