Step-by-step explanation:
Sequence is defined as arrangement f numbers in a specific or defined pattern. Sequence are categorized into
1) Arithmetic
2) Geometric
Arithmetic sequence are characterized by their common difference while Geometric sequence are characterized by their common ratio.
Given a sequance of numbers say;
T1, T2, T3...
The first term "a" of the sequence is T1
Common difference d = T2-T1 =T3-T2
Common ratio = T2/T1 = T3/T2
The formula for calculating nth term of an Arithmetic sequence is expressed as;
Tn = a+(n-1)d
a is the first term
n is the number of terms
d is the common difference
The nth term of a Geometric sequence is expressed as;
Tn = ar^{n-1}
r is the common ratio
Answer:
x
Step-by-step explanation:
Answer:
Age of Jacob is 10 years.
Step-by-step explanation:
Let the age of Jacob = x years and age of Kinsley = y years
Then by first statement " Kinsley's age is 7 years less than twice of Jacob's age"
y = 2x - 7
By second statement " Kensley is 13 years old "
y = 3 years
By putting y = 13 years in the equation
13 = 2x - 7
2x = 13 + 7
2x = 20
x = = 10 years
Therefore, age of Jacob is 10 years.
To find out the median number, you'd have to arrange the numbers in order first.
4,5,8,9,10
Then you'll have to find out the number in the middle, which is 8.
Hope that helps.
For number 1 ↓
A) Cards increase the score by 8 points → <span>5 + 3; 4 + 4</span>
B)Cards decreased the score by 9 points→ <span>-29 + 20; -2 +-7</span>
C) Removing cards that increase the score by 10 points → <span>-4 + -6 & -5 + -5 </span>
D. Positive cards that decrease the score by 18 points. → Well since their aren't "positive card" that'll decrease the score. It might be negative cards which will decrease the scores
For number 2 ↓
Number of Cards → 5 | -3 | -4 | 3|
New cards: 5 | -12 | 4 | 3|
5 + -12 + -4 + 3 = -8
For number 3.↓
12: |-6 | -6|
8: |4 | 4 |
So, the numbers of "cards" hand would: -6 | -6 | 2 | 2| 2| 2 | ; 4| 4
