Find the 10th term of the A.P. 10, 5, 0, — 5, — 10, ...

Answer :

Given: 10, 5, 0, –5, –10,…


To find: 10th term i.e. t10


Here, a = 10


d = a2 – a1 = 5 – 10 = –5


and n = 10


We have,


tn = a + (n – 1)d


t10 = 10 + (10 – 1)(–5)


= 10 + 9 × –5


t10 = 10 – 45


t10 = –35


Therefore, the 10th term of the given is –35.
