Which of th

Answer :

For a series to be in AP, the common difference (d) should be

Equal.


D1 = second term – first term = -6 – (-10) = 4


D2 = Third term - Second term = -2 – (6) = 4


Since common difference is equal the above series is in AP


The next three terms will be the 5th, 6th, 7th.


5th term will be given by


= a + (5-1)d = a + 4d = -10 + 4(4) = 6


6th term is a + (6-1)d = a + 5d = -10 + 5(4) = 10


7th term is a + (7-1)d = a + 6d = -10 + 6(4) = 14
