Answer:
a₁ = 5
a₂ = 8
a₃ = 13
a₄ = 20
Step-by-step explanation:
<u>Given sequence formula</u>
aₙ = n² + 4
<u>Requirement of the question</u>
Find the 4 terms in the sequence
<u>Substitute 4 values into the sequence formula</u>
a₁ = (1)² + 4 = 1 + 4 = 
a₂ = (2)² + 4 = 4 + 4 = 
a₃ = (3)² + 4 = 9 + 4 = 
a₄ = (4)² + 4 = 16 + 4 = 
Hope this helps!! :)

If 1953125 is a square number, then 
By what's given, 
But 
, therefore, our assumption that 1953125 is a square number is wrong.
You can get the different results for the same equation if one of the results is a variable. This is because, in this problem, x=12.
Each of the problems asks you to a similar idea: get a common denominator with the fractions and then subtract.
Problem 1: 28 3/8 - 19 5/6
The factors of 8 are 2, 2, and 2. The factors of 6 are 2 and 3. We take one two that's repeated, two more twos from 8, and a 3 for the common denominator. So, 2 * 2 * 2 * 3 = 24 is the lowest common denominator (LCD).
Now change the fractions to the common denominators
3/8 = ? / 24 We go from 8 to 24 multiplying by 3, so 3 multiplied by 3 is 9.
5/6 = ? / 24 We go from 6 to 24 multipling by 4, so 5 multiplied by 4 is 20.
Then,
28 3/8 - 19 5/6
= 28 9/24 - 19 20/24 <----use common denominators
= 27 33/24 - 19 20/24 <--- borrow from the whole number
= 8 13/24 <---- subtract whole numbers and fraction numerators
Problem 2 works similarly to problem 1, with an LCD of 15.
18 2/5 - 9 13/15
= 18 6/15 - 9 13/15
= 17 21/15 - 9 13/15
= 8 8/15
Thus the differences are 8 13/24 (1st) and 8 8/15 (2nd).
