A Man Was Bor During A Year In Which The Johnson Comet Was Visible In The Sky The Next Time That The Comet Was Visible After The Mans Birth Was In 2005 In What class=

Sagot :

the man was born in year 1998

Explanation:

From the table, the difference in years the comet was seen is 7 years

1956-1949 = 1963 - 1956 = 1970-1963 = 7 years

If the next time the comet appeared was 2005 and a man born during an unknown year was the previous time the comet was seen, then the year the man was born will be the difference between year 2005 and the common difference.

The year the man was born = 2005 - 7years = 1998

To check that the answr is correct: if the man was born in 1998, the next time the comet would be visible after the man's birth is in 7 years time = 1998 + 7 = 2005

Therefore, the man was born in year 1998
