Question

Find the next number in the sequence:
0.1.1,2,3,5,8,13,21,34.__
A
42
B 47
c
55
D 56​

Answer 1

series is 1,2,3,5,8,13,21,34,_

Here we know that every next term is sum of last two previous terms.

So An = A(n-1) + A(n-2)

Now we have to find

A(9) = A(9-1) + A(9-2)

A(9) = A(8) + A(7)

A(9) = 34 +21

A(9) = 55

hence the series becomes

1,2,3,5,8,13,21,34, 55

so c) is correct

Answer 2

Answer:

Example: the next number in the sequence above is 21+34 = 55
