An arithmetic sequence is defined as follows:
Dafna11 [192]

The sum of the first 28 terms in the sequence is 5600

<h3>Sum of sequence</h3>

The sum of sequences are known as series. Given the following

a₁ = 92

a₁ = ai-1 - 8

For the second term

a2 = a1 - 8

a2 = 92 - 8

a2 = 84

Determine the sum of first 28th terms

S28 = 28/2[2(92)+(28-1)(8)]

S28 = 14(184+27(8))
S28 = 14(400)
S28 = 5600

Hence the sum of the first 28 terms in the sequence is 5600

Brian ate 3 granola bars. This is 25% of the total number of granola bars I'm a box. How many granola bars are in a box.
Genrish500 [490]
25% is equal to 1/4. If 3 bars is 1/4 of a box, then there are 3*4 = 12 bars in a box.
