​

Answer 1

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Solution}}}}}}$

first term=a=12

t2=8

t3=4

d=t2-t1

=8-12

= -4

we know that,

TN= a+(n-1)d

t11= 12+(11-1)-4

=12+10(-4)

=12+(-40)

=12-40

=-28

Answer 2

Step-by-step explanation:

tn = a + (n-1) ×d

T(11) = 12 + (11 - 1)× 4

= 12 + 10 × 40

= 12 + 40

= 52

therefore., T (11) = 52
