Answer 1

• First term=a=1
• Common difference=d=-3

Note down the Formula first

$\boxed{\star\sf a_n=a+(n-1)d}$

• Here n is 12

$\\ \sf\ast\Rrightarrow a_{12}=1+(12-1)(-3)$

$\\ \sf\ast\Rrightarrow a_{12}=1+11(-3)$

$\\ \sf\ast\Rrightarrow a_{12}=1-33$

$\\ \sf\ast\Rrightarrow a_{12}=-32$

Option D is correct

Answer 2
