Answer 1

Hope you will get answer

Answer 2

Hint – To find the eighth term, we identify the given sequence as a Fibonacci series. Using its condition we find the 8th8th term.

Step-by-step answer:

Here the given sequence,

1, 1, 2, 3, 5, 8 is a Fibonacci sequence.

Fibonacci sequence is a series of numbers in which each number (Fibonacci number) is the sum of the two preceding numbers.

As,

2 = 1+1

3 = 1+2

5 = 2+3

8 = 3+5

Therefore, next (7th7th) term = Sum of the previous two terms = 5 + 8 = 13

Hence, 8th8th term = 8 + 13 = 21.

Option D is the correct answer.

Note: The key in solving such kind of problems is to identify the kind of sequence given in this case is a Fibonacci Series and to know its definition.

Fibonacci Series typically starts from 0 or 1.
