WebWe know that the formula for the nth term is t n=a+(n−1)d, where a is the first term, d is the common difference. It is given that the nth term is t 15=55 and the first term is a=13, therefore, t n=a+(n−1)d ⇒55=13+(15−1)d ⇒55=13+14d ⇒14d=55−13 ⇒14d=42 ⇒d= 1442=3 Hence, d=3 Solve any question of Arithmetic Progression with:- Patterns of problems > Web9) The solution of the equation x-y=10 and x+y=70 is -----., A) (40,30), , B) (30,40), , C) (10,60), , D) (50,20), , 10) Find the value of Dx for the equation 4𝑥 + 3 𝑦 = 19 and 4 𝑥 −, 3 𝑦 = −11, A) 24, , B) 0, , C) −24, , D) 108, , Q. 1 B) Each of 1 mark, 1) State with reason whether the equation 3𝑥 2 …

S 55 = 3300 .....[Given] We know that, Since S n = `"n"/2`[2a + (n – 1)d] ∴ S 55 = `55/2`[2a + (55 – 1) d] ∴ 3300 = `55/2`[2a + 54d] ∴ 3300 = `55/2` × 2[a + 27d] ∴ 3300 = 55[a + 27d] ∴ a + 27d = `3300/55` ∴ a + 27d = 60 .....(i) Now, t n = a + (n – 1)d highcliffe \u0026 walkford parish councilWebLet the number of terms in the A.P. be n. Then, t n = 101 Since t n = a + (n – 1)d, 101 = 1 + (n – 1) (2) ∴ 101 = 1 + 2n – 2 ∴ 101 = 2n – 1 ∴ 102 = 2n ∴ n = 102 2 = 51 Now, S n = n t t n n 2 ( t 1 + t n) ∴ S 51 = 51 2 ( 1 + 101) = 51 2 ( 102) = 51 × 51 = 2601 ∴ The sum of odd natural numbers from 1 to 101 is 2601. how far is western university from meWeb5) In an AP the T5 = 27 and the T13 = 67, find S20 term (6 marks) 6) In a GP if T2 = 10 and T5 = 1250, find:- T10 This problem has been solved!
