How to find common difference of arithmetic sequence given first and last term?
scoundrel [369]
Yeah there is a way... Lemme give a typical question...
Find the common difference of an arithmetic progression whose first term Is 1 and last term is 1023...

First term = T¹ =a
Last term = Tn = a + (n-1)d

Since your given the values of the first and the last term... You can substitute

Tn = 1 + (1023-1)d

1023 = 1 + 1022d

1022d = 1023 - 1

1022d = 1022

common difference = 1...

So there is a way....

You can get the common difference using the two terms given...

Hope this helped...

Find x if Q is the midpoint of PR, PQ-19, and PR 8x + 14<br>a. 14. B7<br>C 3. D5​
Sonja [21]

Answer:

Step-by-step explanation:

If Q is the midpoint of PR and PQ is 19, that means that QR is also 19 and the total length of PR is 38. Therefore,

PQ + QR = PR and

19 + 19 = 8x + 14 and

38 = 8x + 14 and

24 = 8x so

x = 3

Your choice is C

Please help! Please explain and actually help!
stealth61 [152]

Answer:

17

Step-by-step explanation:

According to the Pythagorean theorem, a^2+b^2=c^2, where a and b are the two legs of a right triangle, and c is the hypotenuse. In this scenario, the two legs are 8 and 15, and we are asked to find the hypotenuse. Plugging the two values in, we have 64+225=c^2, where 64 is 8 squared and 225 is 15 squared. Adding, we have the two values as 289. If you don't know your squares, I suggest you take a look at a list or even memorize your squares until 30, but 289 is actually 17 squared. If c^2=289, then c = \sqrt{289}, which is 17.
