The 28th term of an ap is -5,find the common difference if the first term is 31

klemol [59]

Answer:

The common difference is -4/3.

Step-by-step explanation:

Recall that the direct formula for an arithmetic sequence is given by:

$\displaystyle x_n=a+d(n-1)$

Where n is the nth term, a is the initial term, and d is the common difference.

We are given that the first term a is 31.

We also know that the 28th term is -5. Hence, x₂₈ = -5. Substitute:

$\displaystyle x_{28}=-5=(31)+d(28-1)$

Solve for d. Simplify:

$-5=31+27d$

Thus:

$\displaystyle 27d=-36$

Divide both sides by 27. Hence, the common difference is:

$\displaystyle d=-\frac{36}{27}=-\frac{4}{3}$
