Answer:
thethe answer is the 3rd one
Checking if the sequence is an arithmetic sequence
7 - 1 = 6
13 – 7 = 6
Therefore the sequence is arithmetic, with a_0 = 1 and d = 6
a_n = a_0 + (n-1)d
a_30 = 1 + (29)(6)
= 175
Therefore the 30th term is 175.
6/10 - 1/2...common denominator is 10
6/10 - 5/10 = 1/10 <==
