<u>Question 6</u>

1) $\overline{AB} \cong \overline{BD}$ , $\overline{CD} \perp \overline{BD}$ , O is the midpoint of $\overline{BD}$ , $\overline{AB} \cong \overline{CD}$ (given)

2) $\angle ABO, \angle ODC$ are right angles (perpendicular lines form right angles)

3) $\triangle ABO, \triangle CDO$ are right triangles (a triangle with a right angle is a right triangle)

4) $\overline{BO} \cong \overline{OD}$ (a midpoint splits a segment into two congruent parts)

5) $\triangle ABO \cong \triangle CDO$ (LL)

Answer:

161

Step-by-step explanation:

<u>Given:</u>

$a_1=1\\ \\a_n=3a_{n-1}+2$

<u>Find:</u> $a_5$

First, find the second term. Substitute n=2:

$a_2=3a_1+2=3\cdot 1+2=3+2=5$

Now, find the third term, substitute n=3:

$a_3=3a_2+2=3\cdot 5+2=15+2=17$

Find the 4th term, substitute n=4:

$a_4=3a_3+2=3\cdot 17+2=51+2=53$

At last, find the fifth term, substitute n=5:

$a_5=3a_4+2=3\cdot 53+2=159+2=161$
