Answer:

34

answer of this question

Answer 2

Answer:

53

Step-by-step explanation:

Given series: 15, 60, 17, 58, 23, 52, 53, 40​

This consists of two different series:

1) 15-17-23 and 2) 60-58-52-40

Showing the pattern of the first series:

• 15
• 17=15+1*2
• 23= 17+2*3
• 35= 23+3*4- would be the next term if continued
• 55= 35+4*5 - would be following term if continued

 Showing the pattern of the second series:

• 60
• 58=60-1*2
• 52=58-2*3
• 40=52-3*4
• 20=40-4*5- would be the next term if continued

As we see the only odd number is 53 which doesn't fit in any pattern

Answer is 53
