a

_{1}= 4a

_{2}= 12 = a_{1}+ 8 = a_{1}+ 2^{3}a

_{3}= 28 = a_{2}+ 16 = a_{2}+ 2^{4}a

_{4}= 60 = a_{3}+ 32 = a_{3}+ 2^{5}....

From the above pattern, the recursive formula for this sequence is

a

_{1}= 4a

_{n}= a_{n-1}+ 2^{n+1}for n≥ 2You did not provide the choices in your question. So the above answer may or may not match the choices available to you.
