Answer:
-58
Step-by-step explanation:
The first term (a₁) is 7 and the common difference (d) is 2 - 7 = -5.
Explicit formula of arithmetic sequence: aₙ = a₁ + (n - 1) * d
aₙ = 7 + (n - 1) * (-5) = 7 - 5n + 5 = -5n + 12
Therefore, a₁₄ = -5 * 14 + 12 = -58.

Answer:
12345 < 54321
21435 > 12534
:
Step-by-step explanation:
Given the digits:
1, 2, 3, 4 and 5
We have to use every digit only once and have to make two different five digit numbers.
Using these 5 numbers only once without repetition, we have many numbers possible.
Let us have a look at a few sets and let us compare them.
<u>Set 1:</u> 12345 and 54321
We can see that 12345 is lesser than 54321.
Therefore, we can write (using lesser than sign):
12345 < 54321
<u>Set 2:</u> 21435 and 12534
We can see that 21435 is greater than 12534.
Therefore, we can write (using greater than sign):
21435 > 12534
