Answer:
1. 43, 46, 49, 52, 55, 58, 61, 64 here common difference is 3 ,so values keep on increasing with an addition of 3 .
2. 10, 18, 9, 17, 8, 16, 7, 15 ,here acending order values from 10 is decreasing continuously by 1 and descending order values from 18 are decreasing continuously.
3. 50, 53, 47, 50, 44, 47, 41, 44 ,here first number get added and the next get substracted consecutively, starting from where it left the previous consecutive number with a common difference of 3.
4. 46, 41, 42, 37, 38, 33, 34, 29 ,here first number get subtracted by 5 and the other gets added by 1 consecutively and repeatedly.
5. 90, 84, 80, 74, 70, 64, 60, 54 ,here 1st number difference is 6 2Nd number difference is 4.
6. 70, 72, 64, 66, 58, 60, 52, 52 ,here 1st number 70 -72difference is 2 and 3 no difference is 64-72 is 8 .
7. 5, 7, 10, 14, 19, 25, 32, 40 ,here difference is 2,3,4 consecutively till 32 +8=40 which last difference is 8.
8. 88, 79, 71,64, 58, 53, 49, 46 here difference is adding same like question 7 but in acending order from 46 to 88 79+9=88 which last difference is 49-46=3
9. 36, 42, 37, 43, 38, 44, 39, 45 here 36 ,37 are consecutively repetitiNg and 42 ,43 same condition.
10. 11, 22, 33, 44, 55, 66, 77, 88 it is a table of 11 ,
11x1=11,
11x2=22..

6,14, 5 13, 4, 12 3 ,11 , 2, 10 and so on.
3. 50, 53, 47, 50, 44, 47, 41, 44 next terms are= 38, 41 ,35 , 38 ,32, 35, 29,32 and so on
4. 46, 41, 42, 37, 38, 33, 34, 29 next terms are = 24,25,20,21,16,17,12,13 and so on
5. 90, 84, 80, 74, 70, 64, 60, 54 , next terms= 50,44,40,34,30,24,20,14,10,04,and so on
6. 70, 72, 64, 66, 58, 60, 52, 54 next terms=46,48,40,42,34,36,26 and so on
7. 5, 7, 10, 14, 19, 25, 32, 40 next terms= 49,59,70,82,95,and so on
