Question

find the missing number in series 5 7 10 14 20 26 35 43​

Answer 1

Answer:

55

Step-by-step explanation:

5 +   2 = 7          7 + 3 = 10

10 +  4 = 14       14 + 6 = 20

20 + 6 = 26     26 + 9 = 35

35 + 8 = 43     43 + 12 = 55

Answer 2

Given:

The number in the series are $5$ $7$ $10$ $14$ $20$ $26$ $35$ $43$.

To find:

The missing number in the series.

Step by step explanation:

• The given series is $5$ $7$ $10$ $14$ $20$ $26$ $35$ $43$.
• Let us find the pattern of the series by which the series is made.
• We can see that in this series every consecutive number is added by the multiple of $2$ from the first number of the series. That is,

        $5+2=7$

        $10+4=14$

        $20+6=26$

         $35+8=43$

• We can also see that every consecutive number is added by the multiple of $3$ from the second number of the series. That is,

        $7+3=10$

        $14+6=20$

        $26+9=35$

• In order to find the missing term in the series we need to follow the order the sequence follows.
• The last term in the series in $43$.
• As we know that the numbers in the series is added by the multiple of $3$ we get the missing number as

        $43+12=55$

Final answer:

The missing number in the series $5$ $7$ $10$ $14$ $20$ $26$ $35$ $43$ is $55$.
