Short Answer

Expert verified

The first five terms of the sequence with the general term as $a_{n} = 2^{n} 鈭� 5$ are -3, -1, 3, 11 and 27.

Step by step solution

Step 1. Given information

$\begin{array}{l} Theexpressionforthegeneraltermsisgivenas \\ a_{n} = 2^{n} 鈭� 5 \\ Wehavetofindthefirstfivetermsofthesequence. \end{array}$

Step 2. Find the first term

$\begin{array}{l} Forthefirsttermsubstitute n = 1, \\ 鈬� a_{1} = 2^{1} 鈭� 5 \\ = 2 鈭� 5 \\ = 鈭� 3 \end{array}$

Step 3. Find the second term

$\begin{array}{l} Forthesecondtermsubstitute n = 2, \\ 鈬� a_{2} = 2^{2} 鈭� 5 \\ = 4 鈭� 5 \\ = 鈭� 1 \end{array}$

Step 4. Find the third term

$\begin{array}{l} Forthethirdtermsubstitute n = 3, \\ 鈬� a_{3} = 2^{3} 鈭� 5 \\ = 8 鈭� 5 \\ = 3 \end{array}$

Step 5. Find the fourth term

$\begin{array}{l} Forthefourthtermsubstitute n = 4, \\ 鈬� a_{4} = 2^{4} 鈭� 5 \\ = 16 鈭� 5 \\ = 11 \end{array}$

Step 6. Find the fifth term

$\begin{array}{l} Forthefifthtermsubstitute n = 5, \\ 鈬� a_{5} = 2^{5} 鈭� 5 \\ = 32 鈭� 5 \\ = 27 \end{array}$
