Question

Find the 9th term from the end towards the first term of the ap . 5,9,13,..185

Answer 1

Answer:

Step-by-step explanation:

Here a=5 , d=4, l=185

So, that n is - 185= 5+ (n+1)4

185-5 = 4(n+1)

180/4= n+1

45-1=44=n

Now, 9th term from last = l-(9-1)d

l-8*4= 185-32= 153

So the required term is 153
