IMPORTANT: Statement 2 can be directly inferred from statement 1.
That is, if each term is 4 less than the previous term (e.g., 19, 15, 11, etc) then we can conclude that term2 will be 4 less than term1.
We can also conclude that term3 will be 8 less than term1, and:
term4 will be 12 less than term1.
term5 will be 16 less than term1.
.

.
term239 will be 952 less than term1 (same as statement 2).

So, as you can see, statement 2 DOES NOT PROVIDE ANY EXTRA INFORMATION beyond the information that statement 1 provided.

So, if statement 1 is NOT SUFFICIENT (which is clearly the case), then statement 2 cannot be NOT SUFFICIENT.
More importantly, the statements combined are NOT SUFFICIENT.
