Question

find the missing number in the given figure 142 ? 84 43 67 25 in triangle​

Answer 1

Step-by-step explanation:

43+(6×7)+(6+7)=98

67+(2×5)+(2+5)=84

98+(8×4)+(8+4)=142

Answer 2

98

Here, according to the given information, we are given that,

The first number at the topmost end of the triangle is given as 142.

The last three numbers are given as, 43, 67 and 25.

Now, we have that,

By adding the digits of the number 67, we get,

6 + 7 = 13.

Again, by multiplying the digits of the number 67, we get,

6 × 7 = 42.

Now, adding the sum of the digits of the number 67 as well as the product of the digits of the number 67 to 43, we get,

43 + 42 + 13 = 98.

Now, proceeding in a similar manner, we have that,

By adding the digits of the number 25, we get,

2 + 5 = 7.

Again, by multiplying the digits of the number 25, we get,

2 × 5 = 10.

Now, adding the sum of the digits of the number 25 as well as the product of the digits of the number 25 to 67, we get,

67 + 10 + 7 = 84.

Now, proceeding in a similar manner, we have that,

By adding the digits of the number 84, we get,

8 + 4 = 12.

Again, by multiplying the digits of the number 84, we get,

8 × 4 = 32.

Now, adding the sum of the digits of the number 84 as well as the product of the digits of the number 84 to 98, we get,

84 + 12 + 32 = 142.

Hence, the missing number is 98.
