Two APs have the same common difference. The difference between their 100th terms is 100,what is the difference between their 1000th terms? |
Answer» GIVEN :-
To Find :-
Formula used :-
Solution :-→ Lets First Term of First AP = a → Let Common Difference of First AP = d So, → T₁₀₀ = a + (100 - 1)d → T₁₀₀ = a + 99d ------------ Equation (1) → Lets First Term of Second AP = b → Let Common Difference of Second AP = d So, → T₁₀₀ = b + (100 - 1)d → T₁₀₀ = b + 99d ------------ Equation (2) Given That, Equation (1) - Equation (2) = 100 . So, → ( a + 99d) - (b + 99d) = 100 → a - b + 99d - 99d = 100 → (a - b) = 100 ------------------ Equation (3). . _________________Now, we have to Find difference between their 1000th terms . So, → T₁₀₀₀ = a + (1000 - 1)d ( First Series) . → T₁₀₀₀ = a + 999d ---------- Equation (4) And, → T₁₀₀₀ = b + (1000 - 1)d (Second Series) → T₁₀₀₀ = b + 999d ----------------- Equation (5) . So, Equation (4) - Equation (5) :-→ (a + 999d) - (b + 999d) → (a - b) + (999d - 999d) → (a - b) + 0 → (a - b) PUTTING Value of Equation (3) Here , we get, → 100 (ANS.) |

The sum of first and 15th term of an arithmetic sequence is 38.(a) What is the sum of 7th and 9th term ? |
Answer» The sum of 7TH and 9th TERM is 369.Explanation: Given: sum of first and 15th term = 38 Sum of 7th and 8th term = ? A.P can be written as a, a + d, a + 2d… a + (n – 1)d Let first term = a 15th term = a + (15 – 1)d = a + 14d a + a + 14d = 38 2a + 14d = 38 2(a + 7d) = 38 a + 7d = 38/2 a + 7d = 19 ------(1) [8th term] Therefore, Sum of 7th and 9th term = a + 6d + a + 8d = 19 Common difference, d = 19. Sum of arithmetic series, sₙ = 38 = 38 = 7.5[2a + 266] 38 = 15a + 1995 a = -51.5 So, Sum of 7th and 9th term = 2a + 14d = 2 x -51.5 + 14 x 19 = 369 The sum of 7th and 9th term is 369. To KNOW more: The sum of the 2nd term and the 7th term of an AP is 30. If its 15th ... The sum of the THIRD and the seventh terms of an Ap is 6 and their ... |
