Question

Find the next term in the series

10, 18, 28, 40, 54?

Answer 1

For the given series pattern are as follows:

• $10+8=18$
• $18+10=28$
• $28+12=40$
• $40+14=54$
• $54+16=70$

So each number will follow $(+8,+10,+12,+14…)$. Therefore next number in the given series will be $70$

So the correct answer is $70$

Answer 2

10,18,28,40,54,…?

the difference b/w 1^st  and 2^nd   digit is 8

difference between  2^nd  and 3^rd  is 10 and then  3^rd and 4^th is 12

4^th and 5^th digit  is 14  and last digit and 2^nd last digit is 16

so 54-x=16

so x = 70 

the last digit will be 70
