the answer is 130.

for e.g. 4=68
how is it will show 4*4*4+4=68

same way 5*5*5+5=130, i.e. 5*5*5=125, and 125+5=130

Did nobody see this?
a(index) = ((index-2)*10 + 8) + a(index-1) + a(index-2)
let a(-1) = 4 and a(0) = 0
then
a(1) = (-1*10 + 8) + a(0) + a(-1) = 2
a(2) = (0*10 + 8) + a(1) + a(0) = 10
a(3) = (1*10 + 8) + a(2) + a(1) = 30
a(4) = (2*10 + 8) + a(3) + a(2) = 68
a(5) = (3*10 + 8) + a(4) + a(3) = 136 (unlike 130)
a(6) = (4*10 + 8) + a(5) + a(4) = 252 (unlike 222)

Just an alternative method..

1*2=2

2*5=10.......(5-2=3)

3*10=30........(10-5=5)

4*17=68........(17-10=7)

5*x=?.......(x-17=9)

Therefore x=26

5*26=130

2*2+1=5
3*3+1=10
....

1=02=1*2=0+2(prime)

2+3(prime)=5
2=10=2*5

5+5(prime)=10
3=30=3*10

10+7(prime)=17
4=68=4*17

Similarly, 17+11(prime)=28 (2,3,5,7,11,13-prime numbers)
Therefore, 5*28=140...

here we have,
1^3+1=2
2^3+2=10
3^3+3=30
4^3+4=64
So,
5^3+5=130
i.e, 5 = 130.
