![watermark,type\_d3F5LXplbmhlaQ,shadow\_50,text\_Q1NETiBA6LaFMzM4,size\_20,color\_FFFFFF,t\_70,g\_se,x\_16][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6LaFMzM4_size_20_color_FFFFFF_t_70_g_se_x_16]

方法一，数列通项公式法

![watermark,type\_d3F5LXplbmhlaQ,shadow\_50,text\_Q1NETiBA6LaFMzM4,size\_18,color\_FFFFFF,t\_70,g\_se,x\_16][watermark_type_d3F5LXplbmhlaQ_shadow_50_text_Q1NETiBA6LaFMzM4_size_18_color_FFFFFF_t_70_g_se_x_16]
