Please help me :( no ones helping me :( pls show how you got it too :( thank you ill give you all my points 30 points

1. a. 110

because 5 less than 35 is 30 and 5 less than 10 is 5. it would only make sense for 5 less than 110 is 105

7. D. 54

every other number in the equation is one less (8,7,6,5)

and inbetween those the number is multiplied by 3 (2×3=6, 6×3=18) so then 18×3 =54

the middle left. D. 27

every other one is multiplied by 2 (2×2=4, 4×2=8, 8×2=16) but the first one is multiplied by 3. (1×3=3 3×3=9 9×3=27 27×3=81)

11. A.11

it adds 6 every other (17+6=23, 23+6=29)

for every other first one it adds 4. (7+4=11, 11+4=15, 15+4=19)

12. D. 18

for every other it adds 2.(4+2=6, 6+2=8)

for every other second it adds 6. (6+6=12, 12+6=18, 18+6=24)

15. D. 49

for every other it subtracts 6 (67-6=61, 61-6=55, 55-6=49)

the every other second it divides in half. (32÷2=16, 16÷2=8, 8÷2=4)

18. D. 17

for every other it adds 2.(13+2=15, 15+2=17, 17+2=19)

for every other second it subtracts 2. (21-2=19, 19-2=17, 17-2=15)
