\text{Find the missing term in the following number series-} \text{ } 11 \text{ } 10 \text{ } 19 \text{ } 56 \text{ } 223 \text{ } ?

The pattern is: each term equals previous term × (n+1) - n, where n increases by 1 each step. For 11 to 10: 11×(1+1)-1=21, but this doesn't work. The correct pattern is: subtract 1, multiply difference by 2, subtract 2, multiply by 3, subtract 3, etc. 11-1=10, 10+(10×2-1)=29 (doesn't match). The actual pattern: new term = previous term + (previous term × n - (n-1)), where n increases by 1. 10+(10×2-1)=29 (no). After checking, the pattern is: 11-1=10, 10×2-1=19, 19×3-1=56, 56×4-1=223, 223×5-1=1114. Option E is correct.
