Question

Which of the following defines infinite sequence a.days of the week b.teenage life c.every other day d.first friday of july 2020

Answer 1

Option '(c) every other day' defines infinite sequence.

Step-by-step explanation:

• (a) In case of first option i.e. 'days of a week', it is a finite sequence. Because, there are 7 days in a week which can be counted. So it is a finite sequence.
• (b) Teenage life denotes a person of age 13 to 19 years, which is finite. Hence it cannot be a infinite series.
• (c) When we say every other day, we are denoting any fixed date, so it is countless. Hence, we can say this option satisfies infinite sequence.
• (d) In case of 1st Friday of July 2020, it is only one term i.e. it is not a sequence containing several terms. So, this option is not correct.
