Answer 2

Answer:

– 77

Step-by-step explanation:

nth term of an AP is given by

t ↓ n =a+(n−1)d

= a+(n−1)dIn the given sequence, 'a' = 10, 'd' = -3, 'n' = 30. So, 30th term = t↓30

30 =10+(30−1)(−3)

30 =10+(30−1)(−3) ⟹t ↓30

=10 − 87

= −77.

PLEASE NOTE THIS BEFORE SEEING THE SUM

I HAVE WRITING t ↓ n or t ↓ 30 which is at the pic

because I can't type that in keyboard
