An = 3 + 17(n - 1)
115 = 3 + 17(n - 1)
112 = 17(n - 1)
n - 1 = (112/17)
n = (112/17) + 1
187 = 3 + 17(n - 1)
184 = 17(n - 1)
n - 1 = (184/17)
n = (184/17) + 1
258 = 3 + 17(n - 1)
17(n - 1) = 255
n - 1 = 15
n = 16
-----------------------------
An = 16 + 11(n - 1)
115 = 16 + 11(n - 1)
99 = 11(n - 1)
9 = n - 1
n = 10
187 = 16 + 11(n - 1)
11(n - 1) = 171
n - 1 = (171/11)
n = (171/11) + 1
258 = 16 + 11(n - 1)
242 = 11(n - 1)
n - 1 = 22
n = 23
So the 16th term of the first sequence is equal to 23rd term of the second sequence

c-258. The easiest way to determine the next common term in a 2 sequence problem its pretty simple. Multiply both sequences and add the previous common term that were able to find

c) 258
The next time occurs at 71 + 11*17 = 258
The first series is increasing by 11 and the second series in increasing by 17
In other words, you take 71 and add 17 multiples of 11 to get 258, which would be the same as taking 71 and adding 11 multiples of 17.
