Question

what is the cube of the 15th odd number after 36

Answer 1

Answer:

15th odd number after 36 is 65

cube of 65 =274625

Step-by-step explanation:

The next odd number after 36 is 37

Here we consider an AP with first term a = 37

and common difference d = 2

nth term of an AP is given by

Tn= a + (n-1)d

To find the 15th term

Therefore T₁₅ = 27 + (15 - 1 )2

T₁₅ = 27 + (14 x 2)

T₁₅ = 27 + 28 = 65

Therefore the 15th term is 65

To find the cube of 65

Cube of 65 = 65³ = 274625

Answer 2

The next odd number after 36 is 37.

Here In AP,

first term a = 37 and common difference d = 2

nth term of an AP is given by

Tn= a + (n-1)d

the 15th term,

T₁₅ = 37 + (15 - 1 )2

T₁₅ = 37 + (14 x 2)

T₁₅ = 37 + 28 = 65

Therefore the 15th term is 65

Cube of 65 = 65³ = 274625 ans.
