Yes, correct @D.Ramesh.

Total inductance = L1 + L2 + L3 + L4 + L5.
L1 = 8 L2 = 16 L3 = 32 L4 = 64 L5 = 128.
8 + 16 + 32 + 64 + 128 = 248.
L1 = 8 L2 = 16 L3 = 32 L4 = 64 L5 = 128.
8 + 16 + 32 + 64 + 128 = 248.

Or you could realize that you have a geometric series with 5 terms and use the formula.
s = a* (1-r^n) / (1-r) where in this case a is 8 uH, n is 5, and R is 2.
s = a* (1-r^n) / (1-r) where in this case a is 8 uH, n is 5, and R is 2.

The inductances values are 8,16,32,64,128
Therefore total inductance connected in series = 8+16+32+64+128 = 248
Therefore total inductance connected in series = 8+16+32+64+128 = 248
