23,28,38,?, 62,70 find the missing no using series... and give the reason and step solution please
Answers
The given sequence:
23, 28, 38, ?, 62, 70
We have to find, the value of missing number (?).
Solution:
The pattern follow:
Next number = Previous number + (Sum of the digits).
28 = 23 + (2 + 3)
= 23 + 5 = 28
38 = 28 + (2 + 8)
= 28 + 10 = 38
? = 38 + (3 + 8)
⇒ ? = 38 + 11 = 49
62 = 49 + (4 + 9)
= 49 + 13 = 62
70 = 62 + (6 + 2)
= 62 + 8 = 70
∴ Missing number(?) = 49
Thus, the value of "missing number(?) is equal to 49".
Given:
The sequence: 23, 28, 38, ?, 62, 70
To find:
The value of missing number (term).
Solution:
From given, we have the data as follows.
The sequence is 23, 28, 38, ?, 62, 70
The pattern using which the sequence is created is as follows.
Next number = Previous number + Sum of the digits
28 = 23 + (2 + 3) = 23 + 5 = 28
38 = 28 + (2 + 8) = 28 + 10 = 38
? = 38 + (3 + 8) ⇒ ? = 38 + 11 = 49
62 = 49 + (4 + 9) = 49 + 13 = 62
70 = 62 + (6 + 2) = 62 + 8 = 70
∴ The missing term is 49
