. If the expressions x + 5, 2x, and 4x −17 represent the first three terms of an arithmetic sequence, then determine the numerical value of the 20th term.

The value of 20th term is 150.

Step-by-step explanation:

Since we have given that

Since they are in AP.

So, we know that

So, the first term would be :

common difference would be :

So, the value of 20th term would be :

Hence, the value of 20th term is 150.

try soting them out first

step-by-step explanation:

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
