When the terms of a Geometric Progression (G . P .)

with r = 2 is added to the corresponding

terms of an arithmetic progression (A . P .),

a new sequence is formed . If the first terms

of the GP and AP are the same and the first

three termsof the new sequence are

3, 7 and 11 respectively, find the nth term

of the new sequence
