1.	Which term of the AP 3, 15, 27, 39,.....will be 132 more than its 54th term?
Answer» After now it will be 132+639=771 A = 3n = 54d = 12we know thata + ( n - 1 ) d= 3 + ( 54 - 1 ) 12= 3 + 53 × 12= 3 + 636= 639Now32 + 639 = 771771 = 3 + (n - 1) 12768/12 + 1 = n64 + 1 = nn = 65Therfore 65th term term 132 more than 54th term.
