1)a_{n}=5^{n}\\a_{1}=5^{1}=5\\a_{2}=5^{2}=25\\a_{3}=5^{3} =125\\2)b_{n}=n^{2}\\b_{1}=1^{2}=1\\b_{2}=2^{2}=4\\b_{3}=3^{2}=9

3)c_{n}=frac{1}{2^{n}}\\c_{1}=frac{1}{2^{1}}=frac{1}{2}\\c_{2}=frac{1}{2^{2}}=frac{1}{4}\\c_{3}=frac{1}{2^{3}}=frac{1}{8}

4)d_{n}=4^{-n}\\d_{1}=4^{-1}=frac{1}{4}\\d_{2}=4^{-2}=frac{1}{4^{2}}=frac{1}{16}\\d_{3}=4^{-3}=frac{1}{4^{3}}=frac{1}{64}
