(2/7 + 7/8) x 8/25 ÷ 37/15
Answers
Step-by-step explanation:
What is the next number in this sequence: 1 ,7 ,15 ,25 ,37?
The difference between 7 and 1 is 6. The difference between 15 and 7 is 8. The difference between 25 and 15 is 10. Now, a clear pattern emerges here: starting at 1, we add x, which begins at 6 and increases by 2 with each term. I could just continue the pattern. The difference between 37 and 25 is 12, so the difference between x and 37 should be 14, or x-37=14. Adding 37 to both sides gives x=51. Therefore, the next term is 51. To find the n+1 term in the sequence, you take the n term and add the quantity of the difference between the n term and the n-1 term plus 2, or simplified, f(n+1)=2n-(f

What's the next number in the sequence: 7, -35, -24, 3, 15, 16, 4?
Polynomial sequence
7 = 1 +6
15 = 7 + 8
25 = 15 +10
37 = 25 +12
Second set of differences = +2
Third set of differences = 0
So it is a quadratic equation
y = a.x^2 +b.x + c
Next term = 37 + 14 = 51
Two ways to solve. Just update differences or find equation
c=1 (assuming first value is at x=0), so subtract
Then b=5 (for second value at x=1), so subtract
Then a=1
y = x^2 + 5x + 1
Solve for x=5 , result = 51
Answer:
(2/7 + 7/8) x 8/25 ÷ 37/15
(16+49) /56×8/25×15/37
65/56×8/25×15/37
65/56×8/5×3/37
13/7×3/37
=39/259
