WebIf the initial term of an arithmetic sequence is a 1 and the common difference of successive members is d, then the nth term of the sequence is given by: a n = a 1 + (n - 1)d. The sum of the first n terms S n of an arithmetic sequence is calculated by the following formula: S n = n (a 1 + a n )/2 = n [2a 1 + (n - 1)d]/2. WebIf a1,a2,a3,..... is an A.P. such that a1+a5+a10+a15+a20+a24=225, then a1+a2+a3+.....+a23+a24 is equal to (A) 909 (B) 75 (C) 750 (D) 900. Check
