Step-by-step explanation:

Mean of the origibal set = 20

No. of terms = 10

Sum = Mean x No. of terms

= 20 x 10 = 200

The sum of additional numbers to make the new set of observstion is 4 + 8 + 12...... + 40 = 220

New Sum = 200 + 220 = 420

The no of terms stay the same

New Mean = New Sum/ N

= 420/10

= 42

Step-by-step explanation:

Given : Rule $x^3+7$

To find : Create a number pattern that follows the rule. Use at least three terms in the pattern ?

Solution :

Rule $x^3+7$

Put n=1,

$x^3+7=(1)^3+7$

$x^3+7=1+7=8$

Put n=2,

$x^3+7=(2)^3+7$

$x^3+7=8+7=15$

Put n=3,

$x^3+7=(3)^3+7$

$x^3+7=27+7=34$

Put n=4,

$x^3+7=(4)^3+7$

$x^3+7=64+7=71$

The pattern form is 8,15,34,71 which follows the rule $x^3+7$
