In arithmetic progression;
an = a1 + ( n - 1 ) ∙ d
In this case:
Initial term of arithmetic progression:
a1 = - 4
Common difference:
d = 6
So:
a50 = a1 + ( n - 1 ) ∙ d = - 4 + ( 50 - 1 ) ∙ 6 = - 4 + 49 ∙ 6 = - 4 + 294 = 290
What is the 50th term of the sequence that begins -4,2,8,14
My answer is
296
