5d+d=18
18 divided by 6 is 3 so Sheila has 15 markers and Dave has 3

Sheila has 5 times.
Dave has 1 time.
Together they have (5 + 1) = 6 times.

6 times = 18

Divide each side by 6 : 1 time = 3

Sheila has 5 times = (5 x 3) = <em>15 markers</em>.

Dave has 1 time = 3 markers.

Total = (Sheila + Dave) = (15 + 3) = <u>18 markers</u>.
Check, check , and double check.

A1. 12 i.e option D

A2. 3n-7 i.e option A

A3. -6n+20 i.e option D

A4. -70 i.e option C

Step-by-step explanation:

aₙ = a₁ + (n - 1) × d

aₙ = the nᵗʰ term in the sequence

a₁ = the first term in the sequence

d = the common difference between terms

Using the above formula to solve the first part, we have :

-8 = a₁ + (2-1) × 5

-13 = a₁

a₆ = -13 + (6-1) × 5

a₆ = 12

For the second part, we have :

aₙ = -4 + (n-1)×3

aₙ = -4 + 3n -3

aₙ = 3n-7

For the third part, we have :

a₁=14 ; d=-6

aₙ = 14 + (n-1)×(-6)

aₙ = -6n + 20

For the fourth part, we have :

aₙ = 14 + (15-1)×(-6)

aₙ = -70
