Answer:
im pretty sure it would be a.
Step-by-step explanation:
55x3 = 165, and 12x would mean the money times the amount of used he bought. so therefore it is a.

Answer:
Step-by-step explanation:
As 2 and 7 are the only prime divisors of both 
and 
we know that both can be written as:
Where 
is the set of all natural numbers adding the zero (careful because this part is important as I'll explain next).
We also know that 14 divides both numbers and that is actually the greatest common divisor between them. So we can rewrite a and b as follows:
Why do I write them like this? Because this way is easier to observe that if 
and 
were both greater than zero, then 28 would divide both hence 14 wouldn't be their g.c.d.. Likewise, if 
and 
were both greater than zero, then 98 would divide both and once again, 14 wouldn't be their g.c.d.
So either of them has to be equal to zero. And then we have that
All we have left to do is find the possible values for and so that 
and that only happens if 
and 
Answer:
the 30th term is 239
Step-by-step explanation:
The computation of the 30th term is as follows:
As we know that
a_n = a_1 + (n-1)d
where
a_1 is the first number is the sequence
n = the term
And, d = common difference
Now based on this, the 30th term is
= 152 + (30 - 1) × 3
= 152 + 29 × 3
= 152 + 87
= 239
Hence, the 30th term is 239
