Answer:
an = 2(−4)^(n − 1); all integers where n ≥ 1
Step-by-step explanation:
The equation has the form ...
an = a1(r)^(n-1) . . . . . where a1 is the first term and r is the common ratio.
The first term is given as 2, and the ratio will be the ratio of the first two terms:
r = (-8)/(2) = -4
Terms are numbered starting with n=1, so the formula is ...
an = 2(-4)^(n-1) for n≥1
The nearest tenth is still zero. Reason being you have to start from the right, and once you round the far most 9 to the zero it turns to a one which is too small of a number to round up.
There can be so many of such.
Eg. 38 750 38 835
38 795
38 820
Any of the numbers above when rounded to the nearest hundred would result in 38 800.
The idea is such that to make sure the 100 digit is 7 and the 10 digit is 5 or more.
Or if the 100 digit is already 8, then the 10 digit must be less than 5

-7, and 7
