WebExample 1: If the first term of an AP is 67 and the common difference is -13, find the sum of the first 20 terms. Solution: Here, a = 67 and d= -13 S n = n/2 [2a+ (n-1)d] S 20 =20/2 [2×67+ (20-1) (-13)] S 20 = 10 [134 – 247] S 20 = -1130 So, the sum of the first 20 terms is -1130.

WebIn the given AP, the first term is a = 7 and the common difference is d = 4. Let us assume that 301 is the n th term of AP. Then: T n = a + (n - 1)d 301 = 7 + (n - 1) 4 301 = 7 + 4n - 4 301 = 4n + 3 298 = 4n n = 74.5 But 'n' must be an integer. Hence 301 cannot be a term of the given AP. Answer: 301 cannot be a term of the given AP. reading books on amazon fire
