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.
WebSolution 1 Here , a = 2 , l= 29 and s n = 155 Let d be the common difference of the given AP and n be the total number of terms. Then, T n = 29 ⇒ a + (n-1) d = 29 ⇒ 2 + (n-1) d= 29 .............. (1) The sum of n terms of an AP is given by s n = n 2 [ a + l] = 155 ⇒ n 2 [ 2 + 29] = ( n 2) × 31 = 155 ⇒ n = 10 Putting the value of n in (i), we get: WebWord problems: Sum to n terms of an arithmetic progression.

WebGiven that sum of the first 10 terms of an A.P. is -150. S 10 = -150 And the sum of next 10 terms is -550. So, the sum of first 20 terms = Sum of first 10 terms + sum of next 10 terms S 20 = -150 + -550 = -700 Now, having S 10 = 10/2 {2a + (10 − 1)d} -150 = 5 (2a + 9d) -30 = 2a + 9d 2a + 9d = -30 . . . .
