​

Answer 1

Answer:

nth term of an AP is given by

t

n

=a+(n−1)d

In the given sequence, 'a' = 10, 'd' = -3, 'n' = 30.

So, 30th term =

t

30

=10+(30−1)(−3)

⟹t

30

=10−87=−77.

please take the idea from it

Answer 2

Answer:

-2

Step-by-step explanation:

a=10

d= 7-10

= -3

using formula a+(n-1)d put n =5 so,

5th term = a+4d.

= 10+4(-3)

=10-12

=-2
