The 8th term of an A.P. is zero. Prove that its 38thterm is triple of its 18th term. |
Answer» Answer:-Given: 8th term of an AP = 0 We know that, nth term of an AP = a + (n - 1)dHence, → a + (8 - 1)d = 0 → a + 7d = 0 → a = - 7d -- equation (1)We have to prove: 38th term = 3 * 18th term. → a + (38 - 1)d = 3 [ a + (18 - 1)d ] → a + 37d = 3a + 51d Putting the VALUE of a from equation (1) we get, → - 7d + 37d = 3 ( - 7)d + 51d → 30d = - 21d + 51d → 30d = 30d→ LHS = RHS Hence, Proved.
