Tim is reading a book. on monday he reads 3 pages. on each day after that, he reads triple the number of pages as the previous day. how many pages does ire read on thursday.

The number pages read on Thursday is 81 pages.

Step-by-step explanation:

Hint - This is problem of Geometric Series.

On Monday Tim read 3 pages. He reads triple the number of pages as the previous day.

So on Tuesday he will read = pages, so the series is

As Thursday is the 4th days.

So we have to find the 4th term.

We know that the nth term in a GP is,

where,

a = 1st term = 3,

r = common ratio = 3

n = 4

Putting the values,

its an acute right triangle

step-by-step explanation:

m∠a is 90°

m∠b is 40°
