Question

Find the 8th term of the AP -3,-1,1 ....

Answer 1

a=-3

n=8

d=-1-(-3)

=-1+3

=2

8th term i.e.,

a8=a+(n-1)d

a8=-3+(8-1)2

a8=-3+7×2

a8=-3+14

a8=11

Therefore 8th term of this AP is 11.

Answer 2

Answer:

a=-3

n=8

d=-1-(-3)

=-1+3

=2

8th term i.e.,

a8=a+(n-1)d

a8=-3+(8-1)2

a8=-3+7×2

a8=-3+14

a8=11

8th term of this AP is 11.
