The easiest way to answer this is to try all choices, plug
in values for the 1st term and 2nd term then check if the
answer matches with 5 and 2. (n = 1 and n = 2)
We know that n starts with 1 because that is our 1st
term, we do not have 0th term, therefore that leaves us with 2
choices.
Choice 1: an = 5 − 2(n − 1); all integers where n ≥ 1
n = 1
a1 = 5 – 2 (1 – 1) = 5 – 2 (0)
a1 = 5
n = 2
a2 = 5 – 2 (2 – 1) = 5 – 2 (1)
<span>a2 = 3 (FALSE!)</span>
Choice 2: an = 5 − 3(n − 1); all integers where n ≥ 1
n = 1
a1 = 5 – 3 (1 – 1) = 5 – 3 (0)
a1 = 5
n = 2
a2 = 5 – 3 (2 – 1) = 5 – 3 (1)
<span>a2 = 2 (TRUE)</span>
Therefore the correct answer is:
<span>an = 5 − 3(n − 1); all integers where n ≥ 1</span>
Answer:
Corp A. 320,000
Corp B. 40,000
Corp C. 430,000
Corp C owns the most land, Corp A owns 8 times more land.
Explanation:
3.2.• 10^5 = 3.2 • 100,000 = 320,000
4 • 10^4 = 4 • 10,000 = 40,000
4.3 • 10^5 = 4.3 • 100,000 = 430,000
40,000 < 320,000 < 430,000
320,000 ÷ 40,000 = 8
Elena bought 3 packs of sandwich buns because 8 goes into 24 three times
