Heya !!




A3 = 8



A + 2D = 8 --------(1)


And,




A7 = 24



A + 6D = 64 --------(2)




From equation (1) we get,


A + 2D = 8



A = ( 8 - 2D ) ---------(3)



Putting the value of A in equation (2)




A + 6D = 24




8 - 2D + 6D = 24



4D = 24 - 8



D = 16/4 = 4




Putting the Value of D in equation (3)


A = 8-2D = 8 - 2 × 4




A = 8-8 = 0



First term ( A ) = 0



And,


Common difference ( D ) = 4



Therefore,




A10 = A + 9D = 0 + 9 × 4



A10 = 36.
