Can someone help me with figuring this problem out!

Question

A Street has 13 houses in a row as shown in the figure. Some residents in the first house tested positive for COVID-19. The virus spreads in two ways: it can spread to the next house, or jump directly to the third house. Residents of house number 2 can get infection in only one way, the house number 3 in two ways, the house number 4 in 3 ways, the house number 5 in 5 ways and so on. If the virus only progresses from Left to Right direction, in how many ways can the residents of the house number 13 get infected?

Answer 1

Look at the sequence

house 2 3 4 5

ways 1 2 3 5

Going to be the Fibonacci sequence, so add two numbers to get the next

So 6th house : 3+5=8

7th house : 5+8=13

etc

Keep going until you get to house 13
