Answer:
8th generation: 34 relatives
9th generation: 55 relatives
Explanation:
Fibonacci sequence is a sequence that is in such a manner that each number will be the sum of the two preceding ones.
Thus, to get how many relatives in the 8th generation, we will need to add the number of relatives in both the 6th and 7th generation.
We are given number of relatives in the 6th and 7th generation as 13 and 21 relatives respectively.
Thus;
No. of relatives in 8th generation = 13 + 21 = 34 relatives
Similarly;
No. of relatives in 9th generation is = no. in 7th generation + no. in 8th generation = 21 + 34 = 55 relatives
