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 … 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.

WebYou would do the exact same process, but you would have to SOLVE for "n" (number of terms) first. To do so, you must start with the arithmetic sequence formula: tn = a + d(n −1) Then, sub in all known values. tn = 15 (last term of the sequence), a = 1 (first term), d = 2 (difference between terms) and solve for n like so: 15 = 1 + 2(n −1)

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: hilbert modular surfaceWebIn an AP, the sum of first ten terms is -150 and the sum of next ten terms is -550.
