The negative term of the sequence 65, 62, 59 is

(a) 22
(b) 23
(c) 24
(d) 27

Step-by-step explanation:

Given series is

Since, its an AP series with

First term, a = 65

Common difference, d = - 3

Let assume that nth term of the series be first negative term.

Wᴇ ᴋɴᴏᴡ ᴛʜᴀᴛ,

↝ nᵗʰ term of an arithmetic sequence is,

Wʜᴇʀᴇ,

aₙ is the nᵗʰ term.

a is the first term of the sequence.

n is the no. of terms.

d is the common difference.

Tʜᴜs,

So, Option (b) is correct.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

↝ Sum of n  terms of an arithmetic sequence is,

Wʜᴇʀᴇ,

Sₙ is the sum of n terms of AP.

a is the first term of the sequence.

n is the no. of terms.

d is the common difference.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
