nice to help you

Answer 2

Answer:

t₆ - t₂ = 40

Step-by-step explanation:

d = 10

t₆ = a + ( 6 - 1 ) d

  = a + 5 * 10

  = a + 50 ----(1)

t₂ = a + ( 2 - 1 ) d

  = a + d --- (2)

Therefore,

t₆ - t₂ = a + 50 - ( a + d)

        = a + 50 - a - 10

a will get cancelled out,

       = 50 - 10

       = 40
