The only factors of 73 are itself and one so it is a prime number.
An irrational number is a number that can't be written as a simple fraction such as pi because you can't turn pi into a fraction.
115 x .23= 26.45

Given that the series is given by:
an=5an-1+2
where:
a1=3
then the other terms of the sequence will be:
a2=5a1+2
a2=5*3+2=17
a3=5a2+2
a3=5(17)+2
a3=87
a4=5a3+2
a4=5(87)+2
a4=437
a5=5a4+2
a5=(5*437+2)
a5=2187
hence the sequence will be:
<span>3, 17, 87, 437, 2187
</span>
Answer: <span>a) {3, 17, 87, 437, 2187}</span>
