What should come in place of the question mark (?) in the given series? 2 3 ? 38 102 227
11
Look at differences: 3−2=1=1³, ?−3=8=2³ (so ?=11), 38−11=27=3³ ✓, 102−38=64=4³ ✓, 227−102=125=5³ ✓.
The differences are consecutive cubes (1, 8, 27, 64, 125). The missing term = 3 + 8 = 11.
The correct answer is : 11.
