Find t12 term in an arithmetic progression having t3 = 10 and t10 = −4 .
Marat540 [252]

Answer:

t12= -8

Step-by-step explanation:

t3

a+2d=10 (1)

t10

a+9d=-4. (2)

From (1)

a=10-2d. (3)

Sub into (3) into equ (2)

a+9d=-4

10-2d+9d=-4

10+7d=-4

7d=-4-10

7d=-14

Divide both sides by 7

d=-14/7

d= -2

10=a+2d

10=a+2(-2)

10=a-4

10+4=a

14=a

a=14

t12=a+11d

= 14+11(-2)

=14-22

= -8

t12= -8

Well since the whole (1 pint) is 16 fluid ounces (fl oz) and we only have 7 fl oz, the fraction is 7 over 16; 7/16. This fraction can't be simplified, so 7/16 is in simplest form.
