The equation for finding the equation of an arithmetic sequence is an=a1+(n-1)d, where n is the input for the sequence, a1 is the first term, and d is the difference between each term.
a1= 1/4
d= 1/4
an= 1/4 + (n-1)(1/2) - First you need to distribute the 1/2 to both the n and -1 to get: an= 1/4 + 1/2n -1/2.
Then you need to add like terms (1/4-1/2) to get an=1/2n-1/4. Hope this helps!
Add 26 and 73 = 99 then divide 99 by 6 = 16.5 which is 17 vases
Answer:
6
Step-by-step explanation:
180 ÷ 35 = 5.142857143
rounding it off = 6
Answer:
You can follow the following method, there are other ways to do this too.
Step-by-step explanation:
Taking RHS,
(cosx-sinx+cosx+sinx)/(cos^2x-sin^2) [Taking LCM of den.]
2cosx/cos2x
Taking LHS,
sin2x/cos2x*1/sinx
2sinxcosx/cos2x*1/sinx
2cosx/cos2x
