Question
Write time first five terms of the following sequances whose $n ^{\text {th }}$ terms are:
$a_n=3 n+2$
$a_n=3 n+2$
✓
Answer
$a_n=3 n+2$
Let $n=1,2,3,4,5$, them
First five terms,
$a_1=3 \times 1+2=3+2=5$
$a_2=3 \times 2+2=6+2=8$
$a_3=3 \times 3+2=9+2=11$
$a_4=3 \times 4+2=12+2=14$
$a_5=3 \times 5+2=15+2=17$
