Two situations are shown in fig. (a) and (b) In each case m_(1) = 3 kg and m_(2) = 4 kg . If a_(1), a_(2) are the respective accelerations of the blocks in these situations, then the values of a_(1) and a_(2) are respectively [g = 10 ms^(-2)]

If a_(1), a_(2), a_(3),…, a_(n) are in A.P such that a_(4) - a_(7) + a_(10)= m , then sum of the first 13 terms of the A.P is
