Question
Select the correct answer from the given alternatives.
The value 14C1 + 14C3 + 14C5 + ..... + 14C11 is
Options
214 − 1
214 − 14
212
213 − 14
Solution
213 − 14
Explanation;
[Hint : 14C1 + 14C3 + 14C5 + ... + 14C11 + 14C13 = 214–1 = 213
∴ 14C1 + 14C3 + 14C5 + ... + 14C11 = 213 – 14C13 = 213 – 14.]
