A = 10 , d = 7 -10 = -3 , l = -62. no .of terms = l = a + ( n-1 ) d. -62 = 10 +(n-1)(-3) -72=(n-1)(-3) n-1 =24 n= 25. so, there are 25 terms...in the given AP. n- p+1 => 25-11+1 =15. so..the last term from the last Will be15th term series. so, a15 = 10+(15-1)(-3)=10-42. => -32. so, the last term from the end is -32.
