Answer:

11

Step-by-step explanation:

The common difference of an arith. seq. is the distance between any two adjacent members of the sequence.

The difference (increase) between -1 and 10 is +11.  

as a check, determine whether adding 11 to y = 10 results in 21.  Yes, it does.

The common difference here is 11.

Write a number with two decimals places that is bigger than 4 1/5 but smaller then 4.25 (Could u explain so i can actually under
zubka84 [21]
<u>The possible answers are:
</u>
<u /><u /><u><em /></u>4.21
4.22
4.23
4.24

Explanation:
We want a number between 4 1/5 and 4.25.  We will convert 4 1/5 to a decimal first:

Divide 1 by 5:  1/5 = 0.2.

This makes 4 1/5 = 4 + 1/5 = 4 + 0.2 = 4.2.

We want a number between 4.2, which can be written as 4.20, and 4.25.  Any number between will do, so the possible answers would be 
4.21, 4.22, 4.23, or 4.24.<u />
