Answer:
The answer is below
Step-by-step explanation:
They would be written like this:
Arithmetic Progression:
Explicit formula
Tn = a + (n-1) * d
Recursive formula
Tn = Tn-1 + d
Where a is the first term, d is the common differance and n is the number of terms.
Geometric Progression:
Explicit formula
Tn = a * r ^ (n-1)
Recursive formula
Tn = Tn-1 * r
Where r is common ratio
Answer:
48 is the even number
81 is the square number
13 43 23 are the prime numbers
Answer:
seven nineteen
Step-by-step explanation:
This is because the small hand represents the hour, and it's on 7. So the hour is 7:--. Then the next thing you do is check the big hand, the big hand represents the minutes, the minute hand is just before 20 so it's nineteen. The answer is the big hand 7: + the :19 so this makes 7:19 :D
