b) 132
c) 142
d) 152​

Answer 1

Answer:

Option-B) 132

Step-by-step explanation:

An=a+(n-1) d

Here, d = a2-a1 = 0-(-6) = +6, a = -6

A(24)= -6+(24-1)6

=-6+23×6

=-6+138

=132

Answer 2

Answer:

b)132

Step-by-step explanation:

a24=?

a= -6

d=a2-a1

=0-(-6)

= 0+6

=6

an=a+(n-1)×d

a24= -6+(24-1)×6

a24= -6+23×6

a24= -6+138

a24= 132
