X MATH

sum of 3 consec numberrs is 60 find the smallest no.

find x

x + (x+1) + (x+2)

3x + 3 = 60

3x = 60 - 3

3x = 57

3 3

x= 19 20 21

Find the sum of the Odd consectuive numbers from 4 to 20 (( EVEN - EVEN METHOD ))

20 - 4 = 16

16 / 2 = 8 (There are 8 ODD CONSECUTIVE numbers in between )

5 and 19 -- (odd numbers)

5 + 19 = 24

24 / 2 = 12

12 x 8( the number of consective numbers) = 96

Find the sum of the ODD consecutive numbers from 60 up to 110

110 - 60

50 / 2 = 25 ( consecutive number range)

(smallest ODD numbers in the consecutive list ) 61 + 109 = 170

170 / 2 = 85

85 x 25 = 2125 The sum of the odd consecutive numbers

Find the sum of the Odd consectuive numbers from 45 to 95 (( ODD - ODD METHOD ))

95 - 45 = 50

50 / 2 = 25 + 1 (Because the given is ODD now) = 26

next

95 + 45 = 140 140 / 2 = 70

next would be 70 x 26 = 1,820 FINAL ANSWER
