(21/7) + (3 x 5) = 3 + 15 = 18

8+4+9=21 14+5+2=21 this should be 15+5+2=22 18+1+2=21 this should be 18+1+3=23 the answer is 3 to maintain the sequence, three 3 sets of 3 numbers ,increasing by 1

15/21 in lower terms is 5/7.It is 5/7.

15/18 = (5×3)/(6×3) = 5/6

(21)*(5/7) = (5*21)/7 = (5)*(21/7) = (5)*(3) = 15

15/63 simplifies to 5/21:5/21 = 5 ÷ 21 = 0.238095
