Question

find the 10th term of the Ap. 10+ 9+8..​

Answer 1

Answer:T10=1

Step-by-step explanation:

10th term of the Ap. 10+ 9+8..

nth term of an A.P =Tn = a+(n–1)d

Where

a = first term = T1 =10

d = common difference =T2–T1=9–10= -1

Tn = 10 + (n–1)(-1)

= 10–1n+1

Tn = 11–1n

=> T10 = 11 –1(10)

=> T10 = 11 – 10

=> T10 =1
