AP 6

Calculate the first five items of an arithmetic sequence if it is given:
a₂ – a₃ + a₅ = 20
a₁ + a₆ = 38

Correct answer:

a =  0
a₂ =  0
a₃ =  0
a₄ =  0
a₅ =  0

Step-by-step explanation:

System of equations are non-linear.

The equations have the following integer solutions:

(a+d) – (a+2*d) + (a+4*d) = 20
a + (a+5*d) = 38

Number of solutions found: 1

a₁=14, d₁=2

Our linear equations calculator calculates it.

$a_2=a+d=0$

$a_3=a_2+d=0$

$a_4=a_3+d=0$

$a_5=a_4+d=0$
