Question

find t5 if a=3 and d=-3​

Answer 1

Answer:

-9

STEP BY STEP :

$tn = a + (n - 1)d$

here n=5

a=3

d= -3

by formula=

t5= 3 + (5-1) -3

= 3 +(4)-3

multiplying 4 by -3 we get -12

= 3+(-12)

=3-12

-9

ANS= -9

Answer 2

Answer:

t5 = -9

Step-by-step explanation:

tn = a+(n-1)×d

t5 = 3+(5-1)×(-3)

t5 = 3+4×(-3)

t5 = 3+(-12)

t5 = 3-12

t5 = -9

THE VALUE OF t5 IS -9
