Question

Find the 7th term from the end of A.P. 7, 10, 13,.. 184. A 166 B 169 C 172 D 163​

Answer 1

Answer:

Solution,

First term ( a ) = 7

Common difference ( d) = 10-7 = 3

n th term ( tn) = 184

Then, t n= a + ( n-1 )d

or, 184 = 7 + ( n-1 ) * 3

or, 177 =  ( n-1 ) * 3  

or, n-1 = 59

--> n = 60

So, 7 th term from end =  t 54 = a + 53 d = 7 + 53 * 3 = 166

Ans 166 (A)
