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

-32 is your answer.
