a. 367 b.373 c. 413 d.716​

Answer 1

Answer:

We should add 16

So 357+16= 373

So option B is correct

Answer 2

Answer:

Required term is 373.

Therefore option b is the correct answer.

Step-by-step explanation:

Given series is 343,345,349,357,...

This is a number series.

We want to find next term of the series.

If you look it carefully then you can notice that the given series follows a specific rule.

First term:

343

Second term:

$343 + 2 = 345$

Third term:

$345 + 4 = 349$

Fourth term:

$349 + 8 = 357$

Therefore required fifth term is

$357 + 16 = 373$

This is a problem of Mathematics.

Some important Mathematics formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
