Question

sum of three consecutive integers is 18 find the numbers ​

Answer 1

Step-by-step explanation:

let's three consecutive integers = x, x+1 and x+2

according to question,

x+(x+1)+(x+2) = 18

3x+3 = 18

so, x = 5

hence, 1st integer = 5

2nd integer = x+1 = 6

3rd integer = x+2 = 7 answer

Answer 2

Given:

• Sum of three consecutive integers is 18.

To find:

• Required numbers ?

⠀⠀⠀⠀⠀⠀⠀

Solution:

☯ Let the three consecutive integers be x, x + 1, x + 2. ⠀

$\underline{\bigstar\:{\frak{According\:to\:the\:question\::}}}$

$:\implies\sf x + x + 1 + x + 2 = 18$

$:\implies\sf 3x + 3 = 18$

$:\implies\sf 3x = 18 - 3$

$:\implies\sf 3x = 15$

$:\implies\sf x = \cancel{\dfrac{15}{3}}$

$:\implies{\boxed{\frak{\pink{x = 5}}}}\;\bigstar$

⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Therefore, The three consecutive numbers are :

• x = 5
• x + 1 = 5 + 1 = 6
• x + 2 = 5 + 2 = 7

$\therefore\;{\underline{\sf{The \:three\:consecutive \:numbers\;are\; \bf{5,\:6,\;\sf{and}\;\bf{7}\:}.}}}$⠀
