Question

find the 23th term of the arithmetic sequence -1,-3,-5,-7

Answer 1

hello?

Answer 2

a=-1 d=-2 nth term=a +(n-1)d
23rd term=-1+(23-1)-2=-1-44=-45

Answer 3

thank you , but i have another question also

Answer 4

find the 20th term of the airthmatic sequence 2.5, 5, 7.5, 10 , 12.5

Answer 5

a=2.5 d=2.5
20th term =2.5+19x2.5=50

Answer 6

IF THE FIRST TERM OF AN ARITHMATIC SEQUENCE IS 6, AND 22, WHAT IS THE COMMON DIFFRENCE

Answer 7

umm 22 wat is 22??

Answer 8

THE FIFTH TERM

Answer 9

well then 22=a +4d,22=6+4d,16=4d,d=4

Answer 10

THANKS , If the first term of an arithmetic sequence is 10 and the 13th term is 58, what is the common difference?

Answer 11

umm i guess u shud start pluggin d values in2 d equation a=(n-1)d inorder 2 get a hang at such q's!however d ans is 58=10+12d,d=4

Answer 12

c) boundary dashed; shading outside
d) boundary dashed; shading inside

Answer 13

umm srry bt i m pretty clueless abt boundary curves!!

Answer 14
