Question
Find the first term and common difference of the Arithmetic Progressions whose $n ^{\text {th }}$ term is given below $t _{ n }=4-7 n$
✓
Answer
$a=t_1=4-7(1)$
$=4-7=-3$
$d=t_2-t_1$
$\text { Here } t_2=4-7(2)$
$=4-14-10$
$\therefore d=t_2-t_1$
$=10-(-3)=-7$
$=4-7=-3$
$d=t_2-t_1$
$\text { Here } t_2=4-7(2)$
$=4-14-10$
$\therefore d=t_2-t_1$
$=10-(-3)=-7$
