Explanation

Series 1: 1130-15=1115, 1115+20=1135, 1135-25=1110, 1110+30=1140, so J=1140-35=1105. Series 2: 1=1^1, 2=2^1, 9=3^2, 64=4^3, 625=5^4, so N=6^5=7776. Series 3: differences are 5, 10, 17, 26 (second differences 5, 7, 9), so next difference=37 and L=60+37=97. Then (J+N)-L=(1105+7776)-97=8784.
