Write the first four terms of the arithmetic sequence with a[1] = -6 and d = 4.

The formula for an arithmetic sequence is : a(n) = a+ d(n-1) where a is the value of a(1)/first term and d is the common difference

 
In our case, it is a(n) = -6 + 4(n-1)

a(n) = -6 + 4(n-1)
a(1) = -6
a(2) = -6 + 4(1) = -2
a(3) = -6 + 4(2) = 2
a(4) = -6 + 4(4) = 10
