What is the sum of the arithmetic sequence 3,9,15 if there are 34 terms
luda_lava [24]
First we find the common difference.....do this by subtracting the first term from the second term. (9 - 3 = 6)...so basically, ur adding 6 to every number to find the next number.

we will be using 2 formulas....first, we need to find the 34th term (because we need this term for the sum formula)
an = a1 + (n-1) * d
n = the term we want to find = 34
a1 = first term = 3
d = common difference = 6
now we sub
a34 = 3 + (34-1) * 6
a34 = 3 + (33 * 6)
a34 = 3 + 198
a34 = 201

now we use the sum formula
Sn = (n (a1 + an)) / 2
S34 = (34(3 + 201))/2
s34 = (34(204)) / 2
s34 = 6936/2
s34 = 3468 <=== the sum of the first 34 terms

Kendra has $50 to spend on mittens. she wants to buy as many as possible. If each pair cost $3 how much can see buy?
Verizon [17]

Solution:

<u>Note that:</u>

  • 1 pair of mittens = $3
  • Kendra = $50

<u>We already know:</u>

  • The closest number to 50 and is divisible by 3 is 48.

=> x pair of mittens = $3x = 48

=> $3x = 48

=> x = 48/3

=> x = 16

Kendra can buy <u>16 mittens.</u>
