Question

Which is following square number difference between the 49th even number after 1575 and 70th even number before 1028

Answer 1

Step-by-step explanation:

Given number 1575

next even number a = 1576 , d = 2

$49^{th} \: even\: number = a+48d\\=1576+48\times 2\\=1576+96\\=1672 \:---(1)$

Let b = 1028, d = -2 , f

70th even number before 1028

= 1028 +69(-d)

= 1028 - 69 × 2

= 1028 - 138

= 890 ---(2)

Difference of 1672 and 890

= 1672 - 890

= 782
