Question

How many years have 29 days in February from 2001 to 2100. ( A ) 23 ( B ) 24 ( C ) 26 ( D ) 25

Answer 1

Answer:

24

Step-by-step explanation:

2004 is the first year after 2001 to be a leap year

2096 is the last year before 2100 to be a leap year

A leap year happens every 4 years

a1 = 2004

an = 2096

d = 4

Solve n:

an = a1 + (n - 1)d

2096 = 2004 + (n - 1)4

2096 = 2004 + 4n - 4

2096 = 2000 + 4n

4n = 96

n = 24
