Question

If a1 is -4 and a6 is 6 find d

Answer 1

Answer:

Common difference = 2

Step-by-step explanation:

First term of an arithmetic progression = a

Given that a = -4

nth term of an arithmetic progression = a+(n-1)d

Given that 6th term = a+(6-1)d = a+5d = 6

=>> -4 + 5d = 6

=>> 5d = 6 + 4 = 10

=>> d = 10/5 = 2

=>> d = 2
