If the 2nd and 6th terms are equal, then they must all be the same.
Now, if you mean the sum is 4, then we have
a+d + a+5d = 4
a+2d = a+10d+24
Now solve for a and d and write the sequence.
the second and sixth terms of an arithmetic sequence is 4. the third term is 24more than the 11th term.
Determine the first three terms of the sequence
