WebSolution Let 'a' be the first term and 'd' be the common difference of the given A.P. Now, t 3 = 5 (given) ⇒ a + 2d = 5 …. (i) And, t 7 = 9 (given) ⇒ a + 6d = 9 …. (ii) Subtracting (i) from (ii), we get 4d = 4 ⇒ d = 1 ⇒ a + 2 (1) = 5 ⇒ a = 3 Hence, 17 th term = t 17 = a + 16d = 3 + 16 (1) = 19 Concept: Simple Applications of Arithmetic Progression WebThe 5th term of an AP is 112 and the sum of the first 5 terms is 80. What is the first term and common difference? The formula of a sum of n elements is: n* (a1+an)/2 So for n=5, a5=112: 80 = 5* (a1+a5)/2 => 80 = 5* (a1 + 112)/2 160 = 5*a1 + 560 5*a1 = -400 a1 = -80 The general formula of an AP is: an = a1 + (n-1)*d So for n=5, a1=-8:
