1,3,7,15,27,63,127
it is made of two series placed alternatively
1,7,27,127
5^0 +2 = 3
5^1 + 2 = 7
5^2 + 2 = 27
5^3 +2 =127
3,15,63
2^2 -1 = 3
4^2 - 1 = 15
8^2 - 1 = 64
so by this logic 1st term should be 3 not 1

sorry, but it really depends on the options that are given. What if 27 was not an option
