One of the fractions that’s equal to
is 
<u>Solution:</u>
Given that , we have to find fractions which has the same value as that of the fraction
Now, we know that, there are several fractions with values equal to
To find them, just multiply the numerator and denominator by the same number.

Therefore,
is equal to 
We can do the same with 4, to get
, or any other number beyond that.
Hence, one of the fractions that’s equal to
is 
1) This is not an arithmetic sequence because it has n².
2) To find 5 first terms of this sequence, you can simply substitute n with 1,2,3,4, and 5, and calculate values of a(1),a(2), a(3), a(4) and a(5).
a(n) = 3n²- 1
n=1 a=3*1² - 1 = 3-1=2
n=2 a=3*2² - 1 = 11
n=3 a=3*3² - 1 =26
n=4 a=3*4² - 1 = 47
n=5 a=3*5² -1 = 74
