1.	35 are in A.P8. Find p and g, such that 2p, 2p +q, p+ 4q,
Answer» first term is 2p and no. of terms are 4 common difference should be 2p+q -2p = q so, 35 = a+(4-1)d = a +3d => 35 = 2p +3q but common difference should be 2p+q -2p = q also common difference should be p+4q -2p-q = 3q-p = q => 2q = p so,.. 35 = 2*(2q) +3q=> 7q = 35 , q = 5 aand.. p = 2q = 10 Gud.. thanku for helping me so sweet of u..

Answer»

first term is 2p and no. of terms are 4 common difference should be 2p+q -2p = q so, 35 = a+(4-1)d = a +3d => 35 = 2p +3q

but common difference should be 2p+q -2p = q also common difference should be p+4q -2p-q = 3q-p = q => 2q = p

so,.. 35 = 2*(2q) +3q=> 7q = 35 , q = 5 aand.. p = 2q = 10
