Web19 dec. 2024 · ⇒ a + d = 2 and a + 6d = 22 Solving these two equations, we get a = – 2 and d = 4. S n = [2a + (n – 1) d] ∴ S 30 = [2 × (–2) + (30 – 1) × 4] ⇒ 15 (–4 + 116) = 15 × 112 = 1680 Hence, the sum of first 30 terms is 1680.

WebS36 = 36 2[2×20+(36−1) −2 3] = 18[40−35× 2 3] = 18[40− 70 3] = 18×( 120−70 3) = 6×50 = 300. it satisfies for n = 36. So let's find the sum of terms from 26th to 36th term (the 11 … WebSum of n AP terms = S n = n 2 [ 2 a + ( n − 1) d] Where a is first term of AP and d is difference between two consecutive terms of AP. Calculation: Given series is 2, 4, 6, 8, 10,....... a = 2 and d = 2 Let sum of n terms of AP is 210. Therefore, 210 = n 2 [ 2 × 2 + ( n − 1) 2] ⇒ n 2 + n - 210 = 0 ⇒ n 2 + 15n - 14n - 210 = 0 Web7 uur geleden · Tigers manager A.J.
