Find the sum of 14 + 8 + 2+ ... + ( 274) + (-280).
Musya8 [376]

The sum of the given sequence is -6384.

<u>Step-by-step explanation:</u>

The given Arithmetic sequence is 14 + 8 + 2+ ... + ( 274) + (-280).

  • The first term of the sequence = 14
  • The last term of the sequence = -280
  • The common difference ⇒ 14 - 8 = 6

<u>To find the number of terms in the sequence :</u>

The formula used is n = (\frac{a_{n}-a_{1}} {d})+1

where,

  • n is the number of terms.
  • a_{n} is the late term which is -280.
  • a_{1} is the first term which is 14.
  • d is the common difference which is 6.

Therefore, n =(\frac{-280-14}{6}) +1

⇒ n =( \frac{-294}{6}) + 1

⇒ n = -49 + 1

⇒ n = -48

⇒ n = 48, since n cannot be negative.

∴ The number of terms, n = 48.

<u>To find the sum of the arithmetic progression :</u>

The formula used is S = \frac{n}{2}(a_{1} + a_{n} )

where,

  • S is the sum of the sequence.
  • a_{1} is the first term which is 14.
  • a_{n} is the late term which is -280.

Therefore, S = \frac{48}{2}(14+ (-280))

⇒ S = \frac{48}{2}(-266)

⇒ S = 48 \times -133

⇒ S = -6384

∴ The sum of the given sequence is -6384.
