Answer:
Step-by-step explanation:
Given the sequence :
23, 19, 13, 5, -5.......
From the sequence, the common difference is unequal, as their is a constant Increment in the difference after successive numbers.
19 - 23 = -4
13 - 19 = -6
5 - 13 = -8
-5 - 5= -10
Hence an constant difference of - 2 after each successive difference.
Hence, this is a quadratic sequence
With the formula
an² + bn + c
three hundred thousand twenty-one two hundred nine
Answer:
5 times larger
Step-by-step explanation:
5*10^5 = 500,000
1*10^5 = 100,000
500,000/100,000 = 5
2 7/8 + 2 3/8= 4 10/8, which equals 5 2/8, which is also equal to 5 1/4
