Ans - 155 3= (1×1×1)+ (1×2) 14= (2×2×2)+(2×3) 39=(3×3×3)+(3×4) 84=(4×4×4)+(4×5) So next term will be (5×5×5)+(5×6)= 125+30=155
3=1*3 14=2*7 39=3*13 84=4*21 ?=5*(n) 7-3=4, 13-7=6, 21-13=8, n-21=10 =>n=31 5*31=155 so ans is 155
We have a sequence like...
1^3 +1^2 +1 =1 +1 +1 = 3 2^3+2^2+2=8+4+2 = 14 3^3+3^2+3=27+9+3 = 39 4^3+4^2+4=64+16+4 = 84 5^3+5^2+5=125+25+5 =155
So, the missing number is 155.
3 3 * 4 + 2 = 14 14 14 * 3 - 3 = 39 39 39 * 2 + 6 = 84 84 84 * 1 - 18 = 66
So next number is 66.
119 is the number in the sequence
