with this sequence, u can find the difference by subtracting the terms:
11-4=7
18-11=7
now u know that the sequence goes +7 each term.
u could choose to add 7 manually for 29 times (bc u alrdy have the first 3 terms so 32-3=29) or u could calculate it using the formula in the picture.
with the formula, plug in the terms:
let x be the 32nd term
x = 4 + (32-1)7
x = 4 + (31)5
x = 4 + 155
x = 159
159 is the 32nd term
