Answer:
◻here, note it that the common difference between two consecutive terms of AP is constant
◻The formula for finding the sum of terms in an AP is
Sn =[( n / 2) ( 2a + ( n - 1) d ) ]
S24 =[ (24 /2 )(( 2 (5) + ( 24 - 1) 2)]
=[( 24/ 2) ( 10 + ( 23 x 2 )) ]
=[( 24 / 2 ) ( 10 + 46 )]
. = 24 x 28
= 672
Therefor the sum of first 24 terms of the list of numbers is
\boxed{\textbf{\large{672}}}
