Which term of the AP : 3,15,27,39,... will be 132 more than its 54th term? |
|
Answer» 65th term Hi a = 3, d = 12 first find 54th term so n = 54 . By formula An = a +(n - 1) d so An = 3+(54-1)12 = 639. To find the term from question, 639+132= 771. By using same formula, 771=3+(n-1)12 we get n = 65. |
