this series 1, 94, 3, 81, 6, 69, 10, 58, ?? contain two series 1,3,6,10.... and 94,81,69,58.... 1+2=3 3+3=6 6+4=10 Ans 10+5=15; and other series logic is
94-13=81 81-12=69 69-11=58 next term 58-10=48;
1 94 3 81 6 69 10 58 ??
if we take the series 1 3 6 10 ?? you can find the difference between each number as
3-1=2 6-3=3 10-6=4 15-5=5 tne number should be 15
10-4=6 6-3=3 3-2=1 58+11=69 69+12=81 81+13=94 so ans are 15 cause 15-5=10 and 48 cause 48+10=58
