ఇక్కడ ప్రతి అడ్డు వరసలో అనుసరించే నమూనా:
(1వ సంఖ్య)3 – (2వ సంఖ్య)2 = 3వ సంఖ్య
అడ్డు వరస 1: (1వ సంఖ్య)3 – (2వ సంఖ్య)2 = 3వ సంఖ్య
73 - 132 = 343 - 169 = 174
అడ్డు వరస 2: (1వ సంఖ్య)3 – (2వ సంఖ్య)2 = 3వ సంఖ్య
93 - 252 = 729 - 625 = 104
అదేవిధంగా
అడ్డు వరస 3: (1వ సంఖ్య)3 – (2వ సంఖ్య)2 = 3వ సంఖ్య
113 - 302 = 1331 - 900 = 431
అందువల్ల, "431" అనేది సరైన సమాధానం.
