an = 2^(n+2) - 2
a1 = 2^3 - 2 = 8 - 2 = 6
a2 = 2^4 - 2 = 16 - 2 = 14
a3 = 2^5 - 2 = 32 - 2 = 30
a4 = 2^6 - 2 = 64 - 2 = 62
a5 = 2^7 - 2 = 128 - 2 = 126
a6 = 2^8 - 2 = 256 - 2 = 254
6×2+2=14
14×2+2=30
所以括号内为
62×2+2=126
126×2+2=254
满意请采纳,O(∩_∩)O谢谢~
126,254 6——14 +8
14——30 +8x2
30_62 +8x2x2
6=2的三次方-2
14=2的四次方-2
……
所以后面两个数是126、254
56,14,30,62(126) (254)
