Question

13,19,31,49.... complete the sequence​

Answer 1

Answer:

the correct number is 73

Answer 2

Sequence is

$73, 103, 139, 181...$

GIVEN:- $13,19,31,49....$

TO FIND:- Complete the sequence

SOLUTION:-

In mathematics, a sequence is a chain of numbers that follow a specific pattern.

Each element in a sequence is called a term.

The pattern which the sequence us following are:-

• Next term of the series = Prior term of the next added by the multiple of 6 according to the position of the term in the series.

$13 + (6 \times 1) = 13 + 6 = 19 \\ 19 + (6 \times 2) = 19 + 12 = 31 \\ 31 + (6 \times 3) = 31 + 18 = 49 \\ 49 + (6 \times 4) = 49 + 24 = 73 \\ 73 + (6 \times 5) = 73 + 30 = 103 \\ 103 + (6 \times 6) = 103 + 36 = 139 \\ 139 +( 6 \times 7) = 139 + 42 = 181$

Hence, next terms to the series are 73, 103, 139, 181...
