Question

(0) 7, 5, 3, 1,-1,- 3, ... write the first term and the common difference . also write the next two term in each case

​

Answer 1

Answer:

7,5,3,1,-1,-3,... is an A.P.

t1 = 7 , t2 = 5, t3 = 3 , t4 = 1 ,t5= -1 , t6 = -3

a = t1 = 7 , d = t2 - t1 = 5 - 7 = -2

tn = a+(n-1)d

t7 = 7+(7-1)(-2)

t7= 7+ 6(-2)

t7 = 7 - 12

t7= -5

t8= 7+(8-1)(-2)

t8 = 7+7(-2)

t8=7-14

t8 = -7

the first term(a) is 7

comman difference (d) is -2

and next two terms t7 and t8 are -5 and -7 respectively

Answer 2

Answer:

7,5,3,1,-1,-3,... is an A.P.

t1 = 7 , t2 = 5, t3 = 3 , t4 = 1 ,t5= -1 , t6 = -3

a = t1 = 7 , d = t2 - t1 = 5 - 7 = -2

tn = a+(n-1)d

t7 = 7+(7-1)(-2)

t7= 7+ 6(-2)

t7 = 7 - 12

t7= -5

t8= 7+(8-1)(-2)

t8 = 7+7(-2)

t8=7-14

t8 = -7

the first term(a) is 7

comman difference (d) is -2

and next two terms t7 and t8 are -5 and -7 respectively.
