Given the following three sequences:
1. 2, 4, 6, 8,
ii. 2, 4, 8, 16,
iii. a, a + 2, a +4, a +6, a +
which ones are arithmetic sequences?
i and ii, only
2.
i and iii, only
3.
ii and iii, only
4.
i, ii, and iii

answer:

option 2 - 1 and 3

for ap different is same

1- d= 4-2=6-4=2 -ap

2- not ap it's gp

3- d=2 ap
