Q. Given below is a finite sequence of numbers with an unknown x : 0, 1, 1, 2, 3, 5, 8, 13, x, 34 the value of x is :
Answer: 21
Notes: In the given sequence, (starting from the third number) the succeding number is sum of two just precceding numbers. i.e., $latex 1 = 0 + 1$ $latex 2 = 1 + 1$ $latex 3 = 1 + 2$ $latex \therefore x = 8 + 13 = \underline{21}$ Hence option [D] is the correct answer.
