5 2/3 × 2 3/5 = 5 6/15 answer
-15 I’m pretty sure because if u do the math right it’ll be the answer
d = 3 , a₁₂ = 40 and S
= 7775
In an arithmetic sequence the nth term and sum to n terms are
<h3>• a
![n](https://tex.z-dn.net/?f=n)
= a₁ + (n-1)d</h3><h3>• S
![_n](https://tex.z-dn.net/?f=_n)
=
![\frac{n}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B2%7D)
[2a + (n-1)d]</h3><h3>
where d is the common difference</h3><h3>a₆ = a₁ + 5d = 22 ⇒ 7 + 5d = 22 ⇒ 5d = 15 ⇔ d = 3</h3><h3>a₁₂ = 7 + 11d = 7 +( 11× 3) = 7 + 33 = 40</h3><h3>S₁₀₀ =
![\frac{50}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B50%7D%7B2%7D)
[(2×7) +(99×3)</h3><h3> = 25(14 + 297) = 25(311)= 7775</h3>
