In mathematics, number sequences are classified into three types: arithmetic progression, geometric progression and harmonic progression. Arithmetic sequences have a common difference, geometric sequences have a common ration, while harmonic progression is just the reciprocal of the arithmetic progression.
The first term of the arithmetic sequence is 5, followed by three. Therefore, the common difference is, 3-5 = -2. You use these values to the derived formulas for arithmetic progression. One of these formulas is
An = A1 + (n-1)d
where
An is the nth term in the sequence
A1 is the first term of the sequence
n is the totla number of terms within the sequence
d is the common difference.
In this problem, A1 = 5 and d=2. Substituting to the equation,
An = 5 + (-2)(n-1)
An = 5 - 2(n-1), where n should be more than 1. In order for it to become a sequence, it should contain more than one term.
So, the answer is letter D.
Answer:
C. 500
Step-by-step explanation:
1/10 of 5000 = 1/10 × 5000
= 500
Rearrange the formula to solve for time. Which is the distance over the rate. Then divide 546 meters by 1.3 meters per second. The meter units cancel each other out leaving you with : t: 420.
