Answer:
d = 17
Step-by-step explanation:
The given arithmetic sequence is :
31, 48, 65, 82, ...
We need to find the common difference for this sequence.
First term, a₁ = 31
Second term, a₂ = 48
Common difference = a₂-a₁
= 48-31
= 17
So, the common difference for this arithmetic sequence is equal to 17.
Answer:
45
Step-by-step explanation:
Let the number be X.
So 2/3 of a number would be (2/3)x and 1/5 of the same number would be (1/5)x. Therefore, (2/3)x+(1/5)x=39. Next, you combine like terms by converting the fractions: (10/15)x+(3/15)x=39. Now, you add the fractions. (13/15)x=39. Lastly you divide both sides by 13/15 or multiply both sides by 15/13. x=45. That number would be 45.
<u>If you would like to check</u>, you would do 2/3(45) or 90/3 which is 30 and do 1/5(45) or 45/5 which is 9. 30+9=39
