Firewood is stacked in a pile. The bottom row has 20 logs, and the top row was 14 logs. Each row has one more log than the row a

Lyrx [107]

Since, each row has one more log than the row above it

so, this is arithematic sequence

We are given that

First row is

$=14$

so,

$a_1=14$

Last row is

$=20$

so,

$a_n=14$

Each row has one more log than the row above it

so,

$d=1$

now, we can find number of rows

$a_n=a_1+(n-1)d$

we can plug values

$20=14+(n-1)1$

we can solve for n

$6=(n-1)1$

$n=7$

now, we can find total number of logs

$S=\frac{n(a_1+a_n)}{2}$

now, we can plug values

$S=\frac{7(14+20)}{2}$

$S=119$

So,

Number of logs in the pile are 119........Answer
