You jog for 20 minutes a day, after every week you to add 10 minutes. how many weeks will it take for you to be jogging 1 hour and 30 minutes?

solve with an arithmetic or geometric seuence

Eight weeks

Step-by-step explanation:

Let's write the first few terms of your sequence.

20, 30, 40, 50, …

This is an arithmetic sequence, because there is a constant difference between consecutive terms.

The formula for an arithmetic sequence is

aₙ = a₁ + d(n -1 )

a₁ is the first term, and d is the difference in value between consecutive terms. Thus,

aₙ = 20 + 10(n-1)

You want to find the value of n when aₙ = 90 min.

90 = 20 + 10(n-1)

70 = 10(n-1)

 7 = n - 1

 n = 8

It will take you eight weeks until you are jogging for 90 min.

arithmetic sequence: a sequnce in which the diffrence between any two consecutive terms is the same

step-by-step explanation:

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
