if a1 = 10 and an = an - 1 + 1 then find the value of a4

The value of the fourth element of the series is 13.
In this problem we must use a recurrence formula and a initial value to derive the fourth element of the series. Recurrence formulas are expressions that calculate succesive elements of a series in terms of its previous elements.
Now we proceed to find the value of the fourth element of the series:
n = 2
a₂ = a₁ + 1
a₂ = 10 + 1
a₂ = 11
n = 3
a₃ = a₂ + 1
a₃ = 11 + 1
a₃ = 12
n = 4
a₄ = a₃ + 1
a₄ = 12 + 1
a₄ = 13
The value of the fourth element of the series is 13.
