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

S=119

So,

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