Number of rays subtracted by one and adding all previous numbers. Example : number of rays : 13 13-1=12 1+2+3+4+5+6+7+8+9+10+11+12=78 there are 78 angles in 13 rays. Or if you were given a sequence pattern. Number of rays. Number of angles. 1-0 2-1 3-3 4-6 5-10 6-? 7-? Get number of rays minus 1 then add it to the previous number of angles. 6-1=5 5 + 10 (number of angles in 5 rays) = 15 7-1=6 6 + 15 (number of angles in 6 rays) = 21 -werty-sama
