My first question ever, and my last question yet.
shtirl [24]

Answer:

  • n = {14, 15, 16}

Step-by-step explanation:

<u>This is a sum of the first n terms of an AP:</u>

  • S = (1 + n)*n/2

<u>The true sum is between 92 and 145:</u>

  • 92 < n(n + 1)/2 < 145
  • 184 < n(n + 1) < 290
  • 184 < n² + n < 290
  • 185 < (n + 1/2)² < 291
  • √185 < n + 1/2 < √291
  • 14 ≤ n < 17

<u>Let n = 14</u>

  • S = 14*15/2 = 105

<u>Let n = 15</u>

  • S = 15*16/2 = 120

<u>Let n = 16</u>

  • S = 16*17/2 = 136

The product of two consecutive positive odd numbers is 575. Find the smaller of the two numbers?
KonstantinChe [14]

Answer:

The smaller number is 23

Step-by-step explanation:

Given

Let the odd numbers be x and y [x, being the smallest]

Such that

y = x + 2

and

x * y = 575

Required

Find x

Substitute y = x + 2 in x * y = 575

x * [x + 2] = 575

Open bracket

x^2+ 2x = 575

Equate to 0

x^2+ 2x - 575 =0

Expand

x^2+ 25x -23x- 575 =0

Factorize

x(x+ 25) -23(x+ 25) =0

Factor out x + 25

(x-23) (x+ 25) =0

Solve

x - 23 = 0 or x - 25 =0

x= 23 or x = -25

But x can't be negative.

So:

x= 23
