Web12 apr. 2024 · The nth term in AP series is given by the formula below: T n = a + (n – 1)d Where, n = Number of terms a = First term d = Common difference Now, the condition given becomes, ⇒ a 1 + (a 1 + 6d) + (a 1 + 15d) = 40 ⇒ 3a 1 + 21d = 40 ---- (1) Now, the sum of the first 15 terms is given as: The sum of the n terms is given by the formula: WebA1,A2,A3,....is in AP the write in common terms of a and d. .i.e. A1 = a A2 =a+d A3 =a+2d . . A24 = a+23d summing all we get, 4 (6a+69d) = > 4*225 = 900 perhaps. krunal 52 Points 6 years ago u can also solve in such way, (A1+A24) + (A5+A20) + (A10+A15)=225. THEREFORE 3 (A1+A24)=225 (A1+A24)=75. NOW SUM=24/12 (A1+A24) =900
