Answer:
The 5th number is 13 and the 6th number is 17.
Explanation:
For more difficult question, you have to use this way. the rule for arithmetic sequence is An=a1+d(n-1)
So all you have to do is replace the things.
So, you are looking for the 5th spot, the first term is -3, and the difference is 4, replace the n with the 5.
A5=-3+4(5-1)
5-1 is 4
4*4 =16
A5 =-3+16
16-3=13
A5=13
Do the same for A6 , just instead of the "5's" put "6's".
A6=-3+4(6-1)
6-1 +5
5*4 =20
20-3=17
A6 =17
