The three Consecutive Multiples of 13 is 429 are 130, 143 and 156.
Step-by-step explanation:
Step 1:
Given Data: Sum of 3 consecutive multiples of 13 is 429
Step 2:
Assume:
One number = x
Second Number = x + 13
Third Number = x + 26
x + (x + 13) + (x + 26) = 429
x + x + 13 + x + 26 = 429
3x + 39 = 429
3x = 429 - 39
3x = 390
x = 390/3
x = 130
Step 3:
First Number = 130
Step 4:
Value of (x + 13)
130 + 13
= 143
Second Number = 143
Step 5:
Value of (x + 26)
130 + 26
= 156
Third Number = 156
Step 6:
Check if 130, 143 and 156 are Consecutive Multiples of 13 or not.
130 ÷ 13
= 10
143 ÷ 13
= 11
156 ÷ 13
= 12
