Question

Find the missing terms in series 5,8,7,15, 11,29,17, 50,25,?

Answer 1

Step-by-step explanation:

after performing subtraction. ..from required terms....missing term is 78

Answer 2

The completed series is 5,8,7,15, 11,29,17, 50,25,78,35

• This is a simple twin series.
• There are two series in the given series.
• Let us take the odd terms and we have the series 5,7,11,17,25
• 5+2 = 7, 7+4 =11, 11+6 = 17, 17+8 = 25
• So we have just added 2,4,6,8 (multiples of two) to the first, second, third, and fourth terms respectively.
• Now taking the even terms we have the series 8,15,29,50, x
• Where x is the missing term.
• 8+7 = 15, 15+14 =29, 29+21 = 50, 50+28 = 78 =x
• We have just added the multiples of 7, that is 7,14,21,28 to the first, second, third, and fourth terms respectively.
• Adding 28 to 50 we will have the missing term of the series which is 78
• Adding 10 to 25 we have 35 as the next term of the series
