Vlad [161]

Step-by-step explanation:

<h3>QUESTION:-</h3>

Find 26th term of the A.P --15,-35,-55,-75...

<h3>Solution:-</h3>

First term=a=-15

Common Difference=d=-20

We know that

$\boxed{\sf a_n=a+(n-1)d}$

$\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15+(26-1)(-20)$

$\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15+25(-20)$

$\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15+(-500)$

$\\ \:\:\:\:\sf {:}\dashrightarrow a_{26}=-15-500$

$\\ \:\:\:\:\sf {:}\dashrightarrow {\boxed{\bf a_{26}=-515}}$

Write the decimal number as a fraction
(over 1)
35.375 = 35.375 / 1

Multiplying by 1 to eliminate 3 decimal places
we multiply top and bottom by 3 10's

Solve for x. C=x+a/b

marshall27 [118]

Since you are solving for x, you need to isolate x on one side of the equation. Start by subtracting C from both sides.

0 = x + a / b - C

Subtract x from both sides to have it on the left side of the equation.

-x = a / b - C

Make x a positive number by dividing both sides by negative one.

x = - a / b + C

A better way of writing this answer would be: $x=-\frac{a}{b} + C$ .
