. 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.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.
