Question

What is the 50th term for -7,-2,3 ...?

Answer 1

• Answer:

a(50) = 238

• Explanation:

The constant (diference) = 5

-2 - (-7) = - 2 + 7 = 5

3 - (-2) = 3 + 2 = 5

use formula

a(n) = a + (n - 1)d

a = - 7

n = 50

d = 5

a(50) = - 7 + (50 - 1)5

= - 7 + 49ₓ5

= - 7 + 245

= 238

Good luck !
