Answer:
397
Step-by-step explanation:
lets say there's an eqn which is y = mx + c, x is the term no. (5, 6 in the egs provided), y is the value corresponding to x (17, 21)
to find the 100th term sequence we need to find m and c. m is how much y changes when x increases by 1
in this case we can find m easily (m = 21-17 = 4)
now we have c left so just sub one of the egs given to what we have alrd found
17 = 4(5) + c
17 = 20 + c
c = - 3
so the eqn is y = 4x - 3, and we can solve for when x = 100
y = 4(100) - 3
y = 397
hope this isn't too confusing :^)
