the second quesiton

[sinful dome]

They are added in powers of 2

3+1, 4+2, 6+4, 10+8 (1, 2^1, 2^2, 2^3)

1,2,4,8 is the common difference

so the 8th term is 75 + 64 = 139

[random latch]

yeah i found that but the second quesiton

[sinful dome]

k + 2^n = 1026

Oh nah

Disgusting

[sour fog]

Find 2⁰ + 2¹ + 2² + . . . . 2ⁿ

[bright geode]

The nth term is 2^(n - 1) + 2

[random latch]

can you explain how u got that formula

[bright geode]

2^0 = 1

1 + 2 = 3

Now we are looking for the same pattern

Let’s try the 5th term

Which is indeed 2^4 + 2
