Jeremy weigh a cell phone on a digital scale. write down 113 but forget to record the unit.which unit of measurement is correct

Andrew [12]

Hello! Grams would be the correct measurement. One kilogram is equal to about 2.2 pounds. If you cell phone weighed 113 kilograms it would be 249 pounds! The size of an adult!

One gram is about the weight of a paper clip, so it makes more sense for a cell phone to weigh 113 paper clips.

I hope this helps!

$\boxed { \boxed { a_n = a_1 + d(n - 1)}}$

$a_{14} = -33 , a_{15} = 9,$

$a_{14} = a_1 + d(14 - 1) = -33$
$a_1 + 13d = -33$

$a_{15} = a_1 + d(15 - 1) = 9$
$a_1 + 14d = 9$

So the two equations:
$a_1 + 13d = -33$ ----------------- ( 1 )
$a_1 + 14d = 9$ ----------------- ( 2 )

(2) - (1) :
$d = 42$ ----------------- (Sub into 1)

$a_1 + 13(42) = -33$
$a_1 + 546= -33$
$a_1 = -33 - 546$
$a_1 = -579$

$\boxed { \boxed { a_n = -578 + 42(n - 1)}}$
